I finally saw Troy last night, after letting it sit on my end table for over a month. Go netflix!
In brief, I was disappointed.
The movie had no life in it. Something was missing, and it was missing across the board. The scenes felt play-acted; I wasn't seeing Achilles, I was seeing Brad Pitt acting out his lines. The fights were acceptable but most were lacking any real impact. Even the props seemed off to me, and I can't explain why. Sure, some were awesome, but many just seemed like ... props.
I think Jess put it best, fairly early in the movie. "I should be feeling awed by this, but I'm not."
One other nit -- the movie is rated R. You've got naked people everywhere, but all the "naked bits" are hidden by clever shooting. What is the point of that? It's a distracting flag of disbelief, and while it bothers me in PG-13 movies I can at least understand the point. In an R-rated movie it's unforgivable and pointless.
I've seen worse movies, sure. But I was expecting better than this. I would not recommend it -- you've got better ways to spend 2h45m....
