In any case, it's hard not to like a movie where the heroes build a wall out of corpses.
For the most part they got the core of what being a Spartan was all about right (killing!), but for some reason the Spartan's kept droning on and on about how they were fighting for freedom. What freedom? I'm not a historian, but I really doubt the Spartan's were big on the whole freedom thing. The main characters wouldn't shut up about it though.
That wouldn't have been too bad, but every once in a while they threw in horribly cliched freedom-phrases like "freedom isn't free". Ugh. If you're ever tempted to say that, don't. I will hunt you down and charge you a buck fifty.
