The Good Shepherd (movie)

Saw this movie with my parents last night. Matt Damon plays a CIA spy who is slowly sucked down a slippery slope into soullessness and despair... all without moving a facial muscle. It was definitely a good movie, but the ending was depressing and confusing, and I must confess that I enjoy Matt Damon more when he's being more active (like in the Bourne movies). This movie actually reminded me a bit of The Quiet American, with Brendan Fraser and Michael Caine -- also a good movie about the underworld of spies and what happens to people when they get sucked down into it.
