I enjoyed the hell out of the movie, both as a fan of Tron and a fan of shiny things. I had friends who were being pricks about the price of the movie (we saw the midnight showing, 3D and IMAX. Nobody forced them to come to that showing, nor go balls out on the bells and whistles, but they were still being big whiners) which kind of diminished my enjoyment of the night, but I was seriously enjoying most moments of the movie. The story wasn't phenomenal but hey, neither was the original film's. I didn't come into the movie expecting some amazing work of sci-fi literature, just a pretty cool movie about dudes in computerworld.
Also, CGI Jeff Bridges straddled the line between impressive and creepy as FUCK.
