In order of most hated to least:
Tusk (I cried because it was so bad. I got angry and upset that somebody could make such a bad movie and go through with it. It left a pit in my stomach and made me feel frustrated and angry beyond any reasonable measure. It was the worst, and I've seen Troll 2 and leprechaun.)
The last emperor (3 hours of absolute garbage where nothing happened and nothing made sense. And it won best picture. Over the princess bride. I live in China, and this story was one of the least interesting stories about the emperors they could tell. It sucked so much, my grandmother hated it and thought it was boring and stupid.)
Chappie (had so many chances to be decent, but ended up being cringe and awful. So much is wrong with that movie. My family and I renamed it "Crappie" with white-out on the case and now only make jokes about Chappie's character being mentally impaired, as that has more charm than the real movie.)
Avatar: the last airbender (I need to re-watch this with the idea that it's a comedy in mind, so I can laugh at how terrible it is in every way.)
The battle of five armies (the definition of padding a movie far beyond what is reasonable.)
I haven't seen food fight, but it would be up there.
I put those things above the transformers movies, deliver us from evil (which sucked so much overall), leprechaun, Troll 2, batman and robin, kingdom of the crystal skull, iron man 2 &3, and cool cat saves the kids.
