My wife and I took our daughter to see Up last night. We say the 3D version as it was at the right timeslot for us.
I have to say that I enjoyed the visuals in the movie but I didn't love the movie itself as much as I thought I would. I heard nothing but good things about it and I thought it was just alright. I thought the characters were good, the animation was outstanding, but something about it just didn't set right for me. Maybe because it had so many sad overtones. Not sure.
