Really? Homer himself gets them wrong in the Illiad....
?? The Iliad is about events which "occurred" in the late Mycenaean period or early Dark Ages of Greece. IIRC the description of tactics in the Iliad is reasonably plausible given what we know about the period (which isn't much). If there's a major error in the poem, the only one I can think of is the use of iron swords--they should be bronze.
Maybe you can elaborate, Max.
As for the film, I guess I'm not going to see it.
Well off the top of my head, we know that the greeks didn't ride their chariots into battle, park them, then fight... :-/
In any case, Homer was a storyteller, not a tactician.
