While resting up after a hard week of work, I flipped the channels and came in about five minutes after the start of this film, based on an Isaac Asimov tale, and directed by, of all people, Chris Columbus, that Ron Howard wannabe.
The first hour or so is very good, far better than Spielberg's A.I. Then the film transitions from the robot version of Andrew to a flesh and blood Robin Williams. While the film does not outright tank, it does become a 'Robin Williams' film- i.e.- a tearjerker. But, in a good sense.
The tale is strong enough to overcome the predictability of Williams' character- Andrew- in his quest for humanity and, yes, love. But, with a better script (and a different lead actor), it could have been a great film, rather than a merely good one.
