I was surprised some people didn't like this movie. I totally enjoyed this one. I like most of Soderbergh's films. It's fast-paced, well-written; not all details have to be explained and expressed through dialogues. It's like they trust their audience to be smart enough to understand what's going on. I also like the way the story unfolds gradually. I thought, at first, it was just a simple drug side effect and medical malpractice just to find out later that there are a lot of other things going on. This is more of a psychological thriller. People expecting a lot of blood, action and things blowing up will be greatly disappointed.
