I don't get all the positive reviews for this movie. I found it overlong and I could not find a reason to care about any of the characters. Technically speaking, there was no true heroic character, as it was a bunch of technologically-advanced criminals and their victims. At several points during the movie I was pleading "Go home! Go home!" It had a decent idea but I have to think that Rod Serling (RIP) probably could have done a much better job with this and he would have done it in a shorter time. I really think the writers and producers could have made a tighter film with better and more interesting characters. Christopher Nolan did terrific, terrific work with Batman Begins and The Dark Knight, but this film is unworthy of its success.
