Me too! I like Flynn. Honestly, I don't believe that Tron would be as acclaimed as it is without the character and personality that he brought to the film. If the Tron program alone was written with the task of holding up the entire movie, I don't think it would have turned out as good. I like the whole fighting for the users thing, but by the end of it he is just another cliche hero who saves the girl. Flynn brought life both to the real world and the grid the entire time, and ultimately becomes the unlikely hero through sacrifice. That's what makes the original so interesting. That and everything else of course.
P.S. Flynn Lives!
