Before anything else: the sex.
There is a sex scene in '300: Rise of an Empire' that is an all-timer. Put it right up there on the shelf next to 'Don't Look Now,' 'A History of Violence,' 'Blue is the Warmest Color,' '9 ½ Weeks' and any of the others that make those best-of lists. Actually, put next to that insanity in the pool from 'Showgirls' (you know, with the dolphin statue?), because there's a level of playful absurdity that changes it from a representation of love (or, more accurately, lust) to something of a Broadway choreographer's interpretation of a fight. Like a 'West Side Story' rumble, but with Eva Green moaning and bent over a table with maps and war figurines. A rise of an empire, indeed.
