I saw Troy today and I was very much impressed. It's a good movie with some amazing action scenes. The fight scene with Hector and Achilles was amazing. I have seen bloodier fights, and fights with more intricate, albeit unrealistic moves, but this one looked so fluid and realistic. I liked the horse they used for the movie, it was a nice touch that they used parts from their ships to build it. Sure they made some adjustments to the Iliad to make it more cinematic. A 10 year siege would have bored most people to tears. But I think they could have at least stretched the events to a longer time period, at least 6 months. Just to assemble 1000 ships and all those troops, plus supplies (war movies tend to forget to show supply lines) would have taken at least a few weeks. And I would have stuck with Paris getting killed and Helen being captured and returned to the Greeks. They really skipped some of the feeling of the complete and total destruction of Troy and it's people.
But for a Hollywood version of the epic poem, it came off pretty well. It would have included too many characters to stay true to the story, and it would have made the Lord of the Rings look like a short subject.
