Using ratings from IMDB, redditor ChallengeResponse created a series of charts that explore ‘TV finales that surprised/disappointed’.

ChallengeResponse compared the IMDB ratings of TV series finales to the show’s average episode rating by building a script that he has made available on GitHub.

He then sorted the data by: the greatest difference between average and last episode’s ratings; highest average episode rating; highest last episode rating; and alphabetically.

Television rating data was collected using IMDbPY and visualized in iPython using matplotlib. Source code for iPython notebook is available on GitHub.
