Not arguing - I was just under the impression that replacing all of the track was what they did 2 years ago and why the closed the ride for such a long time (wasn't it close to a year?).
That being said, I do like how it's darker, now. That's how I remember it from when I was a kid where you couldn't tell where you were going. It does kind of suck that you can't look up from the queue at the glowing rockets racing about but I don't remember the glow being all that great in the past. It would have worked well if they used LEDs on it, though, if you were trying to get that effect again.
The new audio seems a bit goofy. I was really hoping for the audio track like at Disneyland's Space Mountain. It's not horrible, but it really doesn't seem to add to the ride, in my opinion.
