I find it a bit annoying that everybody I've talked to who saw this movie seems so excited about it they practically make it their religion (as one friend actually described it as). I've really noticed in the past while that people tend to hear one side of an argument and get all excited about it, believing it in full, without ever actually reading up on the counter-arguments. This is the same problem that leads to all the ignorance towards weed and it's illegal status actually. But anyway, just check out the wikipedia article on it and it'll cite tonnes of problems with the movie from real quantum physicists (citation included).
