I thought the third act was REALLY stupid
Right when the main character comes back as the dead athelete played by Chris Kattan, for me the movie just fell apart as my suspention of disbelief went right out the window. If they had to have him come back in the body of someone else who's already died, I thought at least have it be someone who's just died but who no one knows is dead yet. Instead he comes back as a guy who's in a hospidal and having his organs removed. I mean just think of the upset it would cause if a body that was known to be dead just suddenly sprang back to life without warning.
The rest of the film up to that point was good, but when they got to the reincarnation part, I just went,"What the hell...?"
