I saw it today, and here's my review(and I've read both the Iliad and the Odissey).
The movie overall was very good. The acting was good, and the battle scenes were truly impressive. And I liked the fact that there were no gods walking amog humans.
However here are some flaws, that I see no reason why they happened:
-Why was Achillis in the Horse? He died much earlier. No sense in this decision.
-Why did that gir kill Agamemnon, when in the Odissey Ulisses says that Agamemnon only got killed, by his wife, when he returned home? I think the director want to include some sort of "bad guys get punished" thing, and the movie would get too long if he showed the destiny of the king of kings. Still an odd decision. I also dislike it when he was screaming "burn Troy burn" like a demented psychopat.
-I read the Iliad many years ago, so I might be mistaken here, but I believe Paris should have died. And while watching the movie, I sure wished to see that coward and effeminate Paris dead.
