LOL! This ruined the movie!
The part where 3D hamsters are dancing in a disco club.
It's only a state of mind.
I agree that was stupid, but it didn't really ruin the movie.
If anything, it made for a nice callback to the scene in "Shredderman" director Savage Steve Holland's Better Off Dead when Lane and Monique are at the fast food place and the camera pans over to the claymation burgers.
