This is the worst movie I have ever seen. I felt compelled to write this review however, not because I think the film should be avoided, but on the contrary, I believe everyone should own a copy of "Undefeatable (that barely even sounds like a grammatically correct word)." The plot, the acting, the fighting, and the lines (oh my goodness the lines are great) are so far below even your average C- film that combined, they create a comprehensively miserable whole. Go out and rent this video, buy a case of Pabst Blue Ribbon, call up your buddies, and sit down for what might be one of the more memorable movie experiences of your life.
