I did like AI.
I didn't feel, as I have seen/heard others say, that it was two different movies. I thought it hung together very well and progressed naturally. The AI child was very believable, never seemed to be a "real boy"
very much the programmed simalcrum faithful to his programming. The other people were also well-drawn, adults and chldren, minor and major characters. I also didn't think it drew too dark or nasty vision of the human race, either.
I do hope some engineer see the flick and decides to design a "Teddy" like that, though. I want one.
