I saw Tron Legacy tonight in 3D and enjoyed the movie. I did have a few issues.

First, how they portrayed Clu really irked me. The CGI used to really wasn't good enough for me (see Uncanny Valley.) I kept thinking about things like how the eyes didn't have any life and how the face muscles didn't seem natural.

Also, I'm not sure why Sam was bleeding while on the grid. Blood wasn't used when a program was injured. If Sam's internal organs exist while he is on the grid what is he breathing? Does he have to go to the bathroom?

All that being said, I wonder if there was any talk about making a Tron MMO. I might give Tron Evolution a try on the PC for the online light cycle fights.
