Query: Dumb! Dumb, and Dumber

It's too bad that you don't have negative ratings, because I would give this film a negative five. Absolutely the worst movie ever made. Mekhi Phifer is one of my favorite character actors, and to have him cast in a movie of this low caliber is just regretable. The stereotypical humor was insulting and was not funny. The only thing keeping me from rating this film below a negative five is the fact that the sound and picture quality are good.
