My overall impression after riding is that this attraction only barely succeeds at "making the grade" and that once again, stateside Disney has taken one too many shortcuts in development and made some poor judgements in art direction and execution.
Just wanted to say thanks for the insightful comments. Based on the video, the ride is pretty much what I expected, though. We've been seeing the concept art for a long time, now, and, well--it looks as they said it would. The AA's are pretty impressive. The ice cream hair, well, that's a "sure, that works" or "no, that doesn't work" subjective thing. I'm on the fence.
I think that lighting would go a LONG way, here. Based upon advance publicity, there was a lot of talk about the descent, and how you'd feel like you were going underwater. Well, the lighting deparment has dropped the ball on that one (wonder if it'll change after soft open?). I also thought there would be some video projection, or even scrims a la Haunted Mansion to give the illusion of water depth and color, but it seems right now to be a room of robots. OK, fine--but where's the "plus" factor, the illusion that you can't wait to see, time and again.
From the video, it just seems like a couple of things need tweaking--like something isn't quite working with the Ursula projection at the end or something.
What I appreciate about your perspective, Whylightbulb, is the fact that you worked on Harry Potter. Between that, and what I've been hearing about the Transformers ride, it seems like Universal is spending the money and really going for the WOW factor with it's new projects. Now, this Mermaid ride can be a small dark ride for Fantasyland, something mild, I get that--but as you've pointed out, it's not swinging for the fences even based upon what it is. I'm not asking that the clamshells go upside down or anything, just that there be a few wow moments in there.
Honesly, the attraction looks OK. Pretty much what I was thinking it would be, and I look forward to riding it. I do see some missed opportunities here, even in the budget, and wonder about that as you have.
For me, the big thing about Mermaid in WDW is going to be the exterior, I think that's a big win for the attraction, there. That will add to the overall ambiance and impact.
Fix that lighting in the main scene, and, well, not bad. Still waiting for WDW to announce something on the scale and impact of HP or Transformers, though. Come on, WDI, take the challenge!
