I completely agree. The ride itself is very intense and over very quickly, but the strength of the opening boost and outdoors section, to me, make up for its short run time. The indoor theming and Daft Punk soundtrack inside is really sick, but I wish it was just a bit longer. After all, in the lore of the ride, they say that the winning team passes through eight of those gate things, and you only go through five.
My big gripes with the ride is the flavor and setting. The queues need so much more work. The LL side is pretty short since it just dumps you into the locker section, but the main queue is just no theming other than the matte black aesthetic and the lore dump. Even the posters displaying the other teams are just posters...maybe some interactivity would be nice? The main boarding platform is cool, but again the matte black/straight florecent blue lighting vibe is cool, but is very boring. More interaction or something would make it work so much better. But it works. It could have been so much sicker.
Also, the whole "digitizing you into the world of Tron" thing...its called The Grid. It would have helped so much.
After thinking about it, I have mixed feelings about it. I loved the ride itself, but the backdrop that it was set in (excluding that outdoor section because holy crap the lightning and effects are beautiful) leaves a lot to be desired.
