The Hangover Franchise
The Hangover was a cultural phenomenon for a brief period of time, but the original hype was totally blown out of proportion. All of the follow-up Hangover movies have been critical messes. It's evident that they're trying to rebuild a formula that wasn't even supposed to be perfect from the get-go. Critics went off about the jokes in this franchise, and how they don't stick unless you're the same age you were when the first one came out. Again, we're not bashing the movie, it's just totally overrated.
