What’s a show with an IMDB rating below 8.0 that you liked?

I think IMBD episode ratings are very accurate in 90% of the cases. Overall IMBD ratings however are not accurate. See mr robot/the leftovers/12monkeys. 3 shows that should be much higher rated.

A big reason for a perceived over-rating of a series is self-selection. If somebody watches an episode of a show and they don't like it, they probably just forget about it and don't rate it, so the people who end up rating it will be fans to begin with. It plays into critics too for TV, very few if any TV critics review anywhere close to every major series, so writers end up assigned to stuff that's already up their alley and may be more generous. Then when you get to seasons 2-3+, the only critics left will be ones who like it enough to continue, so you get a lot of inflated scores for post-1 seasons of series. Movies it's less of a thing, not hard to see somebody sitting through a 2 hour movie they dislike and then rating it accordingly, and many critics see basically every wide-release movie.
