I would have to say THE BROTHERS!!! I mean that movie sucked and I still don't know what all the hype was about. I guess you had to watch it with your significant other...but I watched it one Saturday nite over a bowl of Butter Pecan Ice Cream and it was horrible.
In addition...
1 The Titantic
2. Pitch Black
3. Next Friday
4. Down to Earth ((or whatever that movie is called that stars Chris Rock and he dies and comes back as a white man!! I actually fell asleep in the movies on my brothers shoulder)).
