If you want to see a movie that is entertaining and funny, might I suggest you promptly go out and rent "Monty Python and the Holy Grail". Starring Eric Idle, John Cleese, Terry Jones, Micheal Palin, and many others, this movie is full of humor. The problem is, you have to understand British humor, or the movie seems to fall flat on its face.
All in all, it is a very good movie, and I would recomend it to any one who has any semblance of a sense of humor.
