I have not seen it yet, but am intrigued by Hanson’s review. I have, however, read Herodotus, who is immensely entertaining if you can get past the formal style. I was at La Silla when a massive snowstorm hit. There I was, trapped in a small room with nothing but The Histories to entertain me. I was alternating planning out a survey of a dwarf galaxy with reading about Greek city states. And then my altitude-affected dreams were about doing surveys of Greek city states.
Herodotus isn’t, of course, for everyone. But I have also read Gates of Fire, which is more approachable, historically accurate, a quick read and very very good. I heartily recommend it.
