Holy shit! I just watched this last night.
Overall, it was enjoyable. They did take a whole lot of what happened in The Iliad and screwed it up though. A lot of characters randomly dying when they weren't suppose to, the complete lack participation from the Gods and Godesses, etc. I'm a little bit of a Greek Mythology freak, but even with that, I still enjoyed it. One can't help but admire the character of Hektor regardless.
Also, one of the more subtle things I did enjoy was when Paris hands the Sword of Troy to a young boy and says something about how the Kingdom of Troy will always survive if this sword belongs to a Trojan. From what I've read, the Romans were descendants of the Trojans and their kingdom was established by a man who escaped from Troy after the war. Then the Romans eventually conquer Greece and everything comes full circle, so it was nice to see that included even if most people wouldn't think anything of it.
Outside of that, the ending was kind of lame. We all know what happens to Achilles, but if you live under a rock, avoid the next part. Paris of course shoots him in the heel, but instead of dying, he gets up, gets shot 4 or so more times in what would have been his immortal torso and then talks to and kisses his woman for about 10 minutes before randomly falling over. Just didn't seem very epic, didn't even seem like he was dying. Should've included Apollo guiding the arrow and a more realistic death.
*Spoiler*
Agammemnon also gets killed at the end, despite the fact he lived through the war, only to go home and be killed by his wife. So I thought it was interesting they let the woman kill him off at the end.
*End*
Anyway, I thought those subtle little things made it worthwhile and entertaining and being able to see the city of Troy and Hektor, but it really could have been done a lot better. It's not like they couldn't make a Hollywood blockbuster that includes more of the book. It seemed a little empty, but it wasn't bad.
