I can't really say much that hasn't already been said. I really, really enjoyed the first half of the movie. It was very Spielberg-ish and classic blockbuster in the way everything was building up. But... That was it. The build up had no pay off. Laurie's pseudo-sociological spiel was all bark and no bite, pretty underwhelming antagonist. Clooney's character was pretty bland. Robertson's character I really liked but by the end of the movie all she really did was give a cookie cutter solution anyone could have come up with. Also REALLY awkward relationship with Clooney and the 12 year old robot girl.
Key cameo was funny though.
I give it a C, I guess. Enjoyable, but ultimately bland and delivers absolutely nothing in the final act.
