Glenn Close makes this movie to what it is: a superb drama. I really think this movie could have been just avarage, without her acting. Her powerful performance lifts this in a way that draws you into the action, and that you really remember the film afterwards too. I have always liked her, but I have never really understood how truly good she is, before I saw this. See it, if you want to see what good acting is all about, and you won't regret it.
