Wow, from what I'm seeing on the video, the ride's pretty great!
Ursula is a triumph. So is Scuttle. The movements are so fluid and expressive. They remind me of the AAs in the Sinbad ride in TokyoDisney Sea.
But I must agree with others here that Ariel has some issues. She does look scary in some scenes because of her expressions. I think her eyes are opened too wide. An adjustment that would lower her upper eyelid would help a lot.
And yeah, the conehead AA is pretty much a complete flop. Those who remember the movie might possibly get it, but I bet most people will wonder why Ariel is suddenly sporting a beehive hairdo.
It IS odd that the defeat of Ursula was completely left out of the ride. It changes her role completely. Very puzzling.
I wish there weren't so many stationary figures in the ride. IMO, EVERYTHING should be moving. It's like the Imagineers splurged on some ride elements and left the rest begging.
But overall, it's very cute, and some of the effects look dazzling, especially the plunge-you-under-water effect. And the building is beautiful.
