Looks like it could be very good, although, like you said, a bit dramatic. I think I watched a show on that battle once (yes I'm a history buff, especially when it comes to wars), very interesting (300 spartans holding back a Persian army in the hundreds of thousands, because they forced them into a narrow shore by a cliff where only like 4 or 5 men could fight at a time, and since the Spartans were so excellently trained, the overwhelming ratio of Persians to Spartans was barely a factor, they just slaughtered them as they came. Persia finally won because a traitor showed them a secret path through the mountain to the other side of it, so they flanked the Spartans, but they killed tens of thousands of men. Ok, I'll stop giving you a history lesson now
