Fisrt of all, I love IMDB and made this account only because I want to see it keep improving, and this is thing that really annoys me. On the Episode List why not add the individual ratings of each episode like this? It would be SOO much better in my opinion.
IMDb already provides a way to show the ratings for all of the episodes. For instance, for Better Call Saul
(2015– ) (http://www.imdb.com/title/tt3032476/), on the right side of the page is Top-Rated Episodes.
