The computer visuals were great. One thing that I caught, being the complete nerd that I am: if you look closely at the terminal that Sam sits down at before going on-grid, there is a copy of top running. It reports the system uptime as a few days (9?) even though that system was supposed to be up for years. Rebooted Tron for a kernel upgrade? The rest was great though, and I smiled too. I wonder if the author knew how his terminal footage was going to be used...Cillian Murphy's actions were entirely plausible in context.
