This movie is another take on the popular motif of the afterlife. This time, it all starts from a point where it has been proven some part of us goes somewhere when we die and we get what this does to people. It was interesting, it raised some questions about the nature of personal reality and regret, but it was difficult to like almost any of the characters in the film. The "regular guy" lead is just a selfish and self centered ass, while the woman he falls for is almost as bad, the dad is awful, the mother horrible. The only normal person there was his brother, who of course has a simple supporting role. Robert Redford's character was equally obnoxious, but in his case I think it was necessary, as the scientist who apparently thinks only of his work, hurting the people around him.
Bottom line: you work through a lot of painful scenes of obvious attempts at video art and deep meaning, which by their very nature are neither artistic nor meaningful, only to get to the somewhat interesting twist at the end. The movie is watchable, but nothing beyond average.
