Just saw 300 tonight. I came away with a vision of how the first showing must've gone over in Hell:
Shade of Spartan NCO-type: "That was frigging ridiculous! Where was the rest of the army? The Persians looked nothing like that, we all had decent breastplates, and we never broke formation like that!"
Shade of Leonidas: "Shut up and get me more popcorn! That was frigging fantastic! When's the next showing? I gotta see this again!"
