O'Quinn made this movie.
There were a lot of nice elements but O'Quinn was stand out. I'd seen him in the X-files (and probably Millennium though I don't recall.) Even in those small parts he was magnetic.
This was a revelation, however. He drives the intensity of the movie and I couldn't take my eyes off of him when he was in the scene. I'm not sure why his career was not higher profile until Lost.
