Tron: Legacy

Yesterday I finally got the chance to see Tron:Legacy. Overall I felt it was a decently good film. I liked the special effects, and how the movie ended. I did feel there was some inconsistency with the film and the timeline...since in the grid Kevin Flynn mentioned that days there were like minutes in real life...which then made me think about why Kevin Flynn is not dead since he got trapped in the grid when his son Sam Flynn was like 12 years old...And now Sam being 27 years old is meeting his Dad in the grid...so that is one main problem...second problem...if turning off the power to the arcade meant they didnt age i suppose that would take care of this problem...But...then if that were the case how did CLU send out a message to the pager? So there are some holes in the story, or maybe I am over analyzing it.
