I don't think this suggestion has been made already, but it's possible I missed it.
When viewing the list of episodes (the episode guide tab), it's possible to see the average episode rating from x number of people who rated it, but impossible to tell how many people have written reviews for the episode. You have to actually click on the episode to find out how many, or if there are any at all. Would it be possible to add the number of reviews after the episode rating?
Something like (highlighted part would be the addition):
Ratings:7.5/10 from 14 users, 2 episode reviews
