Not that it's a bad movie, it's amazing, but historically inaccurate. For example, did you know that the Spartans owned slaves? Or that the Spartans could've made peace, but instead ought for bloodshed? Or that the Athenians also owned slaves? Persia didn't allow mass slavery. Also, Persia modernized our world. The Persians were actually closer to being on the good side than the Spartans. For some reason Americans look at it as Spartans perilously defending Western values, but actually, Persia was more Western than Greece.
