I agree with that. I rewatched the preview, and I fully get the vibe now after not fully appreciating it. The ride looks extremely well done. It's like The execution of Pooh's Hunny Hunt in that it knows its IP and uses the tech extremely well, but then at a larger scale.
One thing I would like to mention that's not a spoiler is that I couldn't believe how great a concept of having a train split up into multiple trackless vehicles is. I completely overlooked this but it's brilliant. So many things are like out of an actual short with cleverness about.
A park with Rise, Tot, and Mickey frankly makes Hollywood Studios (despite its faults) world-class. Overcrowding is a concern so a new land seems inevitable and will only make it better. Man, Disneyland is going to be legendary come 2022!
