I rode it for the first time recently, and I have to say that personally I was disappointed. It was definitely fun, but not amazing. It's probably my 4th or 5th favorite ride at WDW right now. Aside from being new and only having virtual queue and ILL, I felt it was just lazily themed (other than all the LED lighting) because they just threw some screens up above the queue and had one small preshow room with a screen in the wall.
I also felt like it was definitely too short and ends abruptly. It feels like they got close to finishing it and just said, eh we're out of time, just wrap it up here. For example, The announcer calls out the 8 gates as you go, with them lighting up, and they are spaced pretty far apart at the beginning 1!................2!................ and so on, then it gets to the end and is like 6..7..8..bye! I don't even thing the announcer called out the last 2 or 3 gates. It feels like the ride is building to a big moment in a race, then its just done.
It probably didn't help that I rode Cosmic Rewind first and was blown away. By far the best ride at Disney right now. (Went on it 6 times on my recent trip lol). Great theming, extra theming in the queue with recognizable characters, a very unique ride with a decent story and a changing soundtrack. Just amazing. Whoever designed that ride needs to be hired for 2 more rides in each park ASAP
