From Penny Arcade, a site not for folks afraid of "fancy" language:
300 is a movie about guys who look cool doing things that are awesome, and as such it's hard not to like it. It leverages swank technology in the service of its cinematic mission. Also, there is a portion of the film given over to a creature, equal parts goat and man, who plays a flute inside of a golden tent. So it's the sort of movie that really has something for everyone.
