I'll tell you why so serious

Good movie, but best of all time? Hardly . . .

Excellent and certainly provocative... If nothing else, the film is a real conversation starter.

I enjoyed watching this film and would recommend other to give it a try , (as I am) but this movie, although enjoyable to watch due to the better than average acting fails to add anything new to its storyline that is all too familiar to these types of movies.
