I thought it was excellent. It was set up as a rallying tale told to troops before going into battle and the visuals and the style of the movie really appealed to me.
Being a quarter Greek and all, I'm glad this kind of story can be told now with the advances in filmmaking recently and it won't look like something out of the '70's. Oh, and the actress who plays Gorgo, Lena Headey, is fine as a muh fucka!
