Netflix is a good site for watching movies, though you have to register.
Watching movies in and of itself carries no moral "good" or "bad". You have to consider what kind of impact they type of movie you are watching has on you, and whether or not you watch them compulsively so that you do nothing. But that's you, the movies themselves aren't good or bad.
