You know, I get the same feeling - that the Imagineers splurged on a great AA - Ursula - and a few decent ones like the Ariels and the Scuttles. But that same level of artistry does not carry on throughout the ride. Painfully obvious shortcuts have been taken. It LOOKS like a ride whose budget was cut. And what a shame. It does have its moments, but the Haunted Mansion, Pirates of the Caribbean (especially the Disneyland version) and the Tower of Terror this ride is NOT.
I think Mermaid could have been a much better ride with just a little bit bigger budget. Months after Mermaid opened, Lasseter described a meeting in which a WDI exec proposed a ridiculously low budget (I am assuming for Carsland as he did have to fight to get Carsland a decent budget), and he told the exec that if he was "ok" with a ridiculously low budget then they would do it that way if the exec promised to wait at the exit of the ride and tell guests coming off the attraction what a big success the attraction was because they cut the budget.
Needless to say the exec backed down.
I seriously think Lasseter had seen the problems related to the budget cuts in Mermaid, and he wanted to avoid the same thing happening with Carsland. What other ride opened months before that he could have been talking from experience about?
I can see Lasseter fighting for old time Disney quality in Carsland, after all, Radiator Springs is near and dear to his heart, so he might well have kept his powder dry for that battle. But with Mermaid, I think that the budget was axed as obviously the final scenes don't have that level of detail and polish expected in a Disney dark ride.
Hate to use a political metaphor, but is Mermaid's lavish queue just
"lipstick on a pig?"
Its sad because Mermaid has some great animatronics, but, for example, the lighting on Ariel's face is from above and you get these horrible shadows. Ursula is a great animatronic, but it doesn't help that her cave is so small and she is so close to the ride vehicles, I guess due to limited space. Concept art revealed a gradual transition to Ursula's lair and a larger cave. I think it was little budget cuts like this that added up to a ride being much less than it should be.
The details aren't there for Mermaid, but I have hope they will be fixed in the future.
