The worst movie I've ever seen was Super Mario Bros. I don't even know where to begin; everything about that movie was just gawd awful. Seriously, I saw this movie at the age of four and I knew it was terrible. It did nothing right, and it was a testament to how terribly video games transfer over to the big screen. At close second would be the movie The Fifth Element... :yes:
You can't help but sit there and think "Seriously.WTF am I watching?"
