Not that anyone's looking for another opinion...
I rode it for the first time on Monday. During the first ride, I didn't love it. I could see the original in my head as we were riding, and it felt like we were speeding through all of the parts. (At the time, it felt like the overall running time was a lot shorter than the original. I cynically thought of it as a way to increase capacity.)
I rode it again on Tuesday. Finally, I was able to shake off my mental comparisons to the original. And I loved it. As people have already said, the visuals are beautiful. If you think of it as a medium thrill ride, it's much more enjoyable.
A couple of things just don't work. The truck just feels wrong - it needs to be more worked over to match the theme - you can just see too much of the original truck. And I really, really miss the "crash test" fake-out in the last scene. The first skid out is confusing now, too, as it's not well-explained - it just kind of happens.
But, ignoring those, I definitely prefer it to the original. I don't think I ever rode the original back-to-back - usually, once was enough. But I rode the new version five times over three days (yay, single rider), and I think I'd have ridden it more had I had more time.
The "TRON" theme in some ways feels like more of a throwback to World of Motion. The city visuals are reminiscent of the futuristic city at the end of the ride.
My last ride of the week was fun. I was next to an older couple (60s/70s) who asked me to "help them figure out what to do". (I showed them how to tap the cards.) I wasn't sure at first if they knew what they were getting into, or if they'd enjoy it at all - I dreaded the first skid out as it was happening. But they took it in stride. At the end of the ride - despite having some rain falling during the outdoor part (painful) - they raved. They LOVED it. It sounded like they wanted to ride it again.
