You have to marvel at the utter laziness of the filmmakers though, the fact that it was simply two C.G. hordes running at each other and oh God I'm having flashbacks! Thank you very much!
I'd LOVE for someone knowledgable to make a trilogy on ancient Greece. Perhaps the three most prominent eras of its history, tied together somehow. Can you imagine an actual, no bollocks, no Hollywoodization portrayal of the battle of Thermopylae, or perhaps a mythology-based trilogy?
And yes, I'm aware there's a Thermopylae film coming out, but I don't expect it to be good by any means.
