I think what really bugged me about your review was your comparing Twilight to eating junk food and saying that it's therefore OK. I don't get that. What's so wrong about self-restraint? I guess nowadays self-restraint is generally perceived as being square and uncool. As if, if you don't indulge yourself, you're not really living to fullest.
But I don't think of it that way. I think restraining oneself is just an exercise in self-control; which is like a muscle in that, if you don't use it, it becomes weak and useless. When a person learns to restrain themselves more, they become more capable of controlling themselves, and to a further extent, more capable of controlling their life.
