I saw Freddy Got Fingered thinking it would be the worse movie I would ever see so, with the lowest expectation for a film, it easily surpbumed it and became one of my favorites. It’s pretty much a giant middle finger to Hollywood and, in this respect, succeeds.

In light of this, I would say the worst movie is either Epic Movie or Date Movie since they fail at being what they were meant to be which is actual spoofs even though all they were were movies that ripped off better ones under the disguise of a spoof and added in jokes that have nothing to do with the genres being spoofed.

Edit: I should add that I mean the two are the worst movies to me rather than thinking my subjective taste should be objective.
