If you haven't seen the 300, don't watch the movie "Meet the Spartans." It's a goof on the 300 and other movies, much like the Scary Movie and the Epic Movie. I never saw Scary Movie but I did watch Epic Movie (it goofed on The Lion, Witch and Wardrobe). It had a lot of fun moments but I think Meet The Spartans has to be the best goof movie I've seen in a while.
It followed the 300 movie almost to a tee. I laughed and laughed at some of the stuff they changed. My Brother watched it but didn't think it was funny. Then he heard me laughing a lot and said, "I guess I'll have to watch the 300 to see what's so funny about this one."
