This starts with a great concept about a robot experiencing human emotions and the consequences that would have. The movie also starts off pretty decent by showing how an emotionless robot is pretty scary, but how emotional humans are also pretty scary. Then it turns into a carnivalesque chase/quest, which is funny, exciting and looks amazing: great mid-story. There were a couple of ways I could see this end, so I figured it would lead to something great. And then, when I least expected it, I got to witness the worst ending I'd ever seen in a sci-fi movie (or Indiana Jones 4), guided by a voiceover (!) literally explaining the moral of the story over and over for 20 minutes.

I was willing to look over some plotholes and some annoying characters (yes teddy and mommy, i'm looking at you) because I liked the fact this movie made me think about what it means to be human. But the ending changed this from an above average movie to a terrible movie. It made me ashamed to be a sci-fi fan...
