I have seen Disturbia and thought it was a decent movie. Even with this kind of material I found Shia La Bouef to be a good actor (same for Transformers, actually; found him a bit disappointing in Indiana Jones though, but maybe the competition was bigger in that one
). In my book it's definetely worth a watch.
What apparently aggrevated moist people about this film was, that the fact that it's a remake of rear Window was not made clear in the credits whatsoever...
