Okay, it will never make it into my list of masterpieces, maybe it won't even make it in the "really good movies", but stay assured you'll have a pretty good time watching this, provided that you accept the slaughtering of realism for the sake of a good-conceived story. Right, authistic people are not like Tim. And right, miss Tyler is much more beautiful than good-acting. But the story is interesting, entertaining at times, and thanks to its lack of realism in dealing with authism, can reach a "happy" ending without resorting to any Deus Ex Machina. And that, in today's US thrillers, is really a lot.
