I really like Christiananswers.net because it will also talk about stuff relevant to Christians that the secular sites might not mention. Like if the film has occultic material or if there's blasphemy.
Isn't it Sony who are taking some of their movies and giving you an option to watch a swearing free version? I think it's a great idea although many think it's awful. There are a number of movies I'd love much more if they stopped the swearing! Elysium was one I would have liked if it weren't for the constant bad language!
