Basically, without going into a lot of detail covered by many here already, you get a pretty good idea just from the review summaries for this film that many found it really well done, moody, and a great concept, BUT... unfortunately I felt that it was ultimately watered down by the ending chosen by the film makers (or possibly yet ANOTHER stupid studio interference...)
So, without entering any Spoiler territory, if you can excuse or overlook the completely OBVIOUS and somewhat ham-handed ending, and just sit back and enjoy the rest of the film, it actually is quite good and intriguing, and you probably will like it for the most part. And, Guy Pearce's acting is superb...
But... I REALLY would have given my left nut (the smaller of the two) if they had just left the ending far more ambiguous and moody, just like the rest of this excellent film. I basically gave it about 2 stars less than I would have normally for a film of this overall quality; specifically because of the poor way in which I feel that they handled the ending...
(I undress further, oh, excuse me... I mean, ADDRESS this further in a much more detailed SPOILER laden thread here in the discussion section for this film below...)
