Overrated Movies- Titanic, and while I like them, the Marvel movies.
Overrated TV- Friends, The Office, Parks and Rec, and Seinfeld. Like, STOP. These shows have been done for years and people are still boo-hooing over them and get all stupidly excited every time there's a mini reunion or something.
Hated Movies- I can't speak for everyone, but there are a select few that will go down in history as being the worst, like The Last Airbender, Cutthroat Island, Gigli, Swept Away, etc. This is all based off 1. Horrible reviews and 2. Bombing terribly in the box office.
And bad TV, well...that all gets canceled for the most part and again, can't speak for all, but I hated Seinfeld. I know that's not a hated one, but I can't stand Jerry Seinfeld.
