Dunno if this is a hot take or not but. When it comes to media that is solely ingested (So movies, tv shows, and books) I think the terms "overrated" and "underrated" make no sense.
People just started spewing those words left and right to...idk. Give their opinion more backbone when they just wanna say "I don't like this thing most other people seem to like." Or "I do like this thing most other people don't seem crazy about."
It's fine to be in the minority of either scenario. But when people insist a media is either overrated or underrated cause of their own opinion, it really comes off as self absorbed lmao. "I'm right and everyone else is wrong" type beat. Nevermind the fact this is all about PERSONAL TASTE anyways which will always be subjective as hell.
