It moves me.

I think there is a general consensus - 300 is just incredible (a fine movie site btw). I thought I'd bring together some of our links:
Tobermory's History of Thermopylae
Victor Davis Hanson's Movie Book Intro
VDH With Your Shield or On It column
VDH's lengthier analysis - Last Night at the 300
All glory goes to Tobermory for these links.
Plus: It was my destiny to play Leonidas
