I'm having trouble remembering some movies that I hated, but the joke for me is that since everything costs about 10 bucks, I figured I'd try to sit in to get my money's worth, normally the parts I hate are at the end, but there were two that if anybody was around in Colorado, they would have seen a 230+ dude walking out of the theater at the end, green at the gills, and crying while planning murder for the ones who created the things.
First was Cat in the Hat, one that my handicap sister wanted to watch (she's like my younger sister in mentality, though actaully older than me). I never seen her turn green as well by the end of a movie.
Second was A.I. I was almost screaming at the screen. "WHEN'S IT GONNA END!?!?!"
Third was Transformers 2. I watched the first one and wasn't sure if I hated it or not, watched it again and saw all the pieces that killed my original love for the franchise. When 2 came out, my friend dragged me saying it was better...She...stayed because she wasn't sure if I was going to leave, I couldn't move from my seat because I was foaming at the mouth.
But yeah, after so many bad movies in my life, I *now* figured out that sometimes 10 bucks can be worth the trouble of leaving a theater.
