We all watch a lot of TV shows. Who doesn’t love to spend some free time on the weekend? 

Many online streaming services offer a large number of TV shows, which are at our disposal to watch, at the price of a subscription cost. The major online streaming services across the world are Netflix, Prime Video, Hulu, and Disney+.

TV Shows Analysis 1

We shall have a look at a TV Show data set and perform some Data Exploration and analysis.

The Dataset

The data ” TV shows on Netflix, Prime Video, Hulu and Disney+ ” can be found here.

The dataset contains a large number of TV shows from the above-mentioned streaming services. Regarding, the features, the dataset contains:

1. Name of the TV Show

2. The year in which the TV Show was produced

3. Target age group

4. IMDB Rating

5. Rotten Tomatoes percentage score

6. 1 or 0 feature indicating whether the TV Show is available on a particular Streaming service.

The dataset is not that feature-rich, but it can tell us a lot about TV Shows.

Let us start with exploring the dataset, by getting started with the code.

Getting Started with the Code

Let us start by importing the libraries.

#Importing libraries
import re
import numpy as np 
import pandas as pd 
import seaborn as sns
import matplotlib.pyplot as plt
import random
from wordcloud import WordCloud, STOPWORDS
import nltk
from nltk.sentiment.vader import SentimentIntensityAnalyzer

Now, let us read the data.

#reading the data

The dataset looks like this.

TV Shows Analysis data head

Let us look at the overall dataset.

#looking at the data
data info TV Shows Analysis

There are a lot of missing values. This data has various TV Shows and their ratings etc. The “%” from rotten tomatoes must be removed and the “+” from age ratings must be removed. The data has to be cleaned properly to do the proper analysis. We will try to do an overall analysis of the TV Shows and understand the trends.

Data Cleaning

Let us get started with data cleaning, it is an important part of the whole process.

#Converting the percentages to number
data['Rotten Tomatoes'] = data['Rotten Tomatoes'].str.rstrip('%').astype('float')
#Removing the "+" sign from age rating
data["Age"] = data["Age"].str.replace("+","")
#Conveting it to numeric 
data['Age'] = pd.to_numeric(data['Age'],errors='coerce')

Now, the data should have been cleaned.

#Final data

Let us look at the cleaned data.

clean data TV Shows Analysis

But, there is a lot of missing values. We need data points with complete data, and the incomplete ones can be removed.

#only the data will complete column values available
#later use

Age Analysis



age analysis TV Shows Analysis
18+ = 376 shows
16+ = 359 shows
7+ = 177 shows
13+ = 7 shows

Thus, we can assume that most shows are for a mature audience. There aren’t many shows for kids here in the data.

Analysis based on Title Names

We will analyze the title names of the TV Shows. This dataset lacks genre or a plot summary of the TV Shows, so we shall work with the text data provided, that is just the Title Names.

#Taking the values
#Joining into a single string
text=' '.join(titles)

Output: 100723

Hence, the text data is quite long.

#How it looks

#Removing the punctuation
text = re.sub(r'[^ws]','',text)

Now, the punctuation has been removed. Now the text looks like this.

#Punctuation has been removed

Title Word Frequency

We will tokenize the words and find out the frequency of each word. This will give us an idea of how many times a word appears in a title, and also give the words which appear maximum in a title.

#Creating the tokenizer
tokenizer = nltk.tokenize.RegexpTokenizer('w+')
#Tokenizing the text
tokens = tokenizer.tokenize(text)
#now we shall make everything lowercase for uniformity
#to hold the new lower case words
words = []
# Looping through the tokens and make them lower case
for word in tokens:
#Stop words are generally the most common words in a language.
#English stop words from nltk.
stopwords = nltk.corpus.stopwords.words('english')
words_new = []
#Now we need to remove the stop words from the words variable
#Appending to words_new all words that are in words but not in sw
for word in words:
    if word not in stopwords:

Now, we get the frequency distribution of the words.

#The frequency distribution of the words
freq_dist = nltk.FreqDist(words_new)

So, now we plot the frequency distribution.

#Frequency Distribution Plot


TV Shows Analysis title world frequency

The plot is not very clear in the image, but I shall leave the link to the Kaggle Notebook, please have a look there.

Some observations:

  • The maximum seen word is love, so we can say titles do have romantic/love-oriented names.
  • Other frequent words are the world, life, adventure, wild, family, story, etc.
  • These are common elements of day-to-day life and hence they are common in the titles.
  • No stopwords as we removed them.

Now, let us make some wordclouds.

#converting into string
res=' '.join([i for i in words_new if not i.isdigit()])


WordCloud with 100 words.

wordcloud = WordCloud(
plt.title('TV Show Title WordCloud 100 Words')


TV Shows Analysis wordcloud

Now, let us try 500 words.

wordcloud = WordCloud(
plt.title('TV Show Title WordCloud 500 Words')


TV Shows Analysis wordcloud 2

Some of the key observations are:

  • Love, world, girl, life, day, family, secret, etc occupy large spaces.
  • As they occupy large spaces, this means they have a high frequency.
  • This shows that a large number of tv shows will have some sort of these components.

Now, let us look into the numeric data.

Analysis of Numeric Data

First, we plot the year of production of the TV Shows. This gives us an idea of the general timelines.

#overall year of release analysis
sns.distplot(data["Year"],kde=False, color="blue")


TV Shows Analysis numeric data

So, as we can see, mainly new TV Shows, especially after 2010. We can understand that most of the content is catered for a younger audience.

Let us now look at the IMDB ratings.

IMDB Rating Data

print("TV Shows with highest IMDb ratings are= ")


TV Shows with highest IMDb ratings are= 
3023                             Destiny

Name: Title, dtype: object

Now, the top 20 shows with the best ratings.

#barplot of rating
sns.barplot(x="IMDb", y="Title" , data= data.sort_values("IMDb",ascending=False).head(20))


IMDB Rating Data

Now, the TV shows with the worst ratings.

#barplot of rating
sns.barplot(x="IMDb", y="Title" , data= data.sort_values("IMDb",ascending=True).head(20))



Well, these are some of the worst-rated TV Shows.

Let us look at the overall IMDB rating data. Having a look at the overall data will show the data distribution.

#Overall data of IMDb ratings
plt.figure(figsize=(16, 6))
plt.title("IMDb Rating Distribution")


IMDb Rating Distribution

Rotten Tomatoes Scores

Now, we proceed with the Rotten Tomatoes scores.

#barplot of rating
sns.barplot(x="Rotten Tomatoes", y="Title" , data= data.sort_values("Rotten Tomatoes",ascending=False).head(20))


Rotten Tomatoes Scores

Now, a look at the worst scores.

#barplot of rating
sns.barplot(x="Rotten Tomatoes", y="Title" , data= data.sort_values("Rotten Tomatoes",ascending=True).head(20))



Now, let us see the distribution of the scores.

#Overall data of Rotten Tomatoes scores
plt.figure(figsize=(16, 6))
sns.scatterplot(data=data['Rotten Tomatoes'])
plt.ylabel("Rotten Tomatoes score")
plt.title("Rotten Tomatoes Score Distribution")
Rotten Tomatoes Score Distribution

The breaks in the data are the missing data points, which we removed.

Overall, we can see that the data has many types of values. I have done a lot of Data Exploration, the full of it can be found in the Kaggle notebook. i will share the link.

TV Show Clustering based on ratings

Now, we shall cluster the TV shows based on the IMDB rating and Rotten Tomatoes score. First, we start by taking the data.

#Taking the relevant data
ratings=data[["Title",'IMDb',"Rotten Tomatoes"]]

The data looks like this:


So, we only have the name of the TV Show and the ratings.


We see that there are much data that is missing. But for undergoing the process, we need complete data. So we shall delete the data which has missing values and only work on data that is complete.

#Removing the data

Important thing is that IMDB data is on a scale of 0-10, and Rotten Tomatoes data is on a scale of 0-100. But data on different scales might not lead to proper clustering, so we convert the IMDb data into a scale of 0-100, that is, we shall multiply it by 10.

#New data



Let us now proceed with clustering, by taking the input data.

#Input data
X=ratings[["IMDb","Rotten Tomatoes"]]

Let us now see, how the data looks like.

#Scatterplot of the input data
sns.scatterplot(x = 'IMDb',y = 'Rotten Tomatoes',  data = X  ,s = 60 )
plt.xlabel('IMDb rating (multiplied by 10)')
plt.ylabel('Rotten Tomatoes') 
plt.title('IMDb rating (multiplied by 10) vs Rotten Tomatoes Score')


scatter plot

KMeans is one of the simple but popular unsupervised learning algorithms. Here K indicates the number of clusters or classes the algorithm has to divide the data into. First, when starting, the algorithm selects random centroids. These centroids are used as the beginning points for every cluster. The positions of the centroids are determined by repeated calculations.

#Importing KMeans from sklearn
from sklearn.cluster import KMeans

Now we calculate the Within Cluster Sum of Squared Errors (WSS) for different values of k. Next, we choose the k for which WSS first starts to diminish.

for i in range(1,11):
#The elbow curve
plt.plot(range(1,11),wcss, linewidth=2, color="red", marker ="8")
plt.xlabel("K Value")



This is known as the elbow graph, the x-axis being the number of clusters, the number of clusters is taken at the elbow joint point. This point is the point where making clusters is most relevant.

#Taking 4 clusters
#Fitting the input data
#predicting the labels of the input data
#adding the labels to a column named label
ratings["label"] = y

Now, let us look at how the clusters look like.

#Scatterplot of the clusters
sns.scatterplot(x = 'IMDb',y = 'Rotten Tomatoes',hue="label",  
                 palette=['green','orange','red',"blue"], legend='full',data = ratings  ,s = 60 )
plt.xlabel('IMDb rating(Multiplied by 10)')
plt.ylabel('Rotten Tomatoes score') 
plt.title('IMDb rating(Multiplied by 10) vs Rotten Tomatoes score')


IMDb rating(Multiplied by 10)


  • The cluster at the top is surely the best TV Shows, they have high scores by both IMDb and Rotten Tomatoes.
  • The middle two are good and average TV Shows. There are outliers, and in some cases, some TV Shows have been rated high by one but rated low by the other.
  • The outliers are mainly caused by the fact that say IMDb rated them well, but Rotten Tomatoes rated them badly.
  • The bottom cluster is usually the TV Shows with bad ratings by both, but there are some outliers.

I displayed all the data in the notebook. For, having a look at the entire code, please visit this link on Kaggle: TV Shows Analysis.

Thus, we had a look at a very interesting dataset on a wide variety of TV Shows.
