It was an excellent film! Even aside from its message, it was striking, unusual and spectacular to look at. Some of the scenes looked like freizes from Greek temples or urn paintings, beautifully staged and super dramatic.
The use of sepia tones and other colour techniques made it visually stunning. I also liked that "ready to rumble" rock and roll type music when they were suiting up for battle. I haven't seen or even heard of the comic 300, but it might be work a look.
