@Akka: You summed my thoughts very well
I also liked the humand aspect, the doubting heroes. It wasn't a dumb hero glorification, rather showed a quite dark side of war heroes.
Also most of the actors played very well. Bard Pitt was good as the de-illused hero, Peter O'Toole gave a great performance, especially at the scene where we asked Achilles for his sons body. Was a sad, but very importent scene.
Eric Bana gave a good Hector, showing a hero who foughts not for fame and glory, but his family and county.
Orlando Bloom was a little bit to much Legolas, and i'am somewhat bored by his two and a half facial expressions he offers. Was o.k. in LOTR, because elves aren't too emotional, but here it was somewhat limiting.
Diane Kruger looked quite nice, but thats it was. Personally i liked the other two girls more.
In summery i think the film was great. It wasn't a historical film accurate to the ilias, but who expected this eigther. It told a good story, which wasn't lost between the battles as in many other films.
[edit] And for the realist: The siege was very short in the film, but the time mentioned in the ilias (10 years) was way too long. There is IMO no way the city and the siege force would have survived so long. The city needs surrounding land for food, which would not work with a besieging army next to it. The army itself would need also food, and stealing from the land does no work 10 years long. Not to forget that diceases and epedemies where a big threatening factor to any siege. I thing any time spawn longer that a year is fictional at this time.
