I was totally surprised at how great this film.You could feel your paranoia rise as the film went on and as you gradually learned the details of the real situation.

It was OK. I don't see why everyone loves it so much. It wasn't very smart or deep or well-directed.

Each character in this movie — down to the smallest one — is an individual rather than a type, prone to spontaneous changes of mood and sometimes amusing outbursts of pettiness or ill humor.

The film's masterful storytelling did its job. The message was clear. No need to overdo.
