Ranking Shows by Season using IMDB

I enjoyed this recent post by Matt Zoller Seitz ranking the first 14 seasons of The Simpsons. I wondered how this ranking would compare to a ranking based on episode ratings on IMDB. I did some tinkering with node.js and jsdom and came up with this. Sorting the output (and eliding non-existent seasons) yields:

8.34 average rating for season 6
8.33 average rating for season 5
8.31 average rating for season 7
8.26 average rating for season 4
8.18 average rating for season 8
8.16 average rating for season 3
8.01 average rating for season 2
7.91 average rating for season 9
7.82 average rating for season 1
7.63 average rating for season 10
7.39 average rating for season 12
7.35 average rating for season 11
7.17 average rating for season 23
7.10 average rating for season 16
7.09 average rating for season 18
7.04 average rating for season 13
6.98 average rating for season 19
6.96 average rating for season 17
6.96 average rating for season 15
6.92 average rating for season 20
6.91 average rating for season 22
6.90 average rating for season 21
6.90 average rating for season 14

I didn't do anything fancy like try to weight ratings by the number of votes, but the results are still interesting, and pretty similar to Zoller Seitz's ranking. To try another show, just change the URL in the script to the IMDB URL for the show with /eprate tacked on the end.
