I saw 300 this weekend. It was awesome, on many levels. Its a little bloody, and deserving of its R rating, but don't worry its nowhere near as violent as Sin City was either. But it was masterfully filmed too, the camera work, the choreography and movements of everyone during the battles, and the story it has to tell, which is actually a true story too and the movie tells it pretty accurately, a little exaggerated for a movie of course, but pretty accurately. Its a masterpiece.
