Man, I went and saw it tonight.
My paper gave it a 9/10. Ebert gave it ** out of 4.
I gotta say, I agree with my local newspaper reviewer on this one.
I REALLY liked it. It had funny parts, action, drama...the works. One thing I really liked was the lack of a "love" story that went on between the two main human characters. It seems like there's gotta be a LOVE story of some kind in EVERY movie anymore...and the lack of one made this movie all the more enjoyable than it already was.
The robot is really cool...I can't really go into alot of detail about the things I really liked about him without giving away some portions of the movie.
If you like sci-fi at all, go see this one. Will Smith did a pretty good job in it as well. I liked his character, but not as much as Sonny, the robot.
