That's so interesting to me - Mermaid is such a fascinating case study in dark rides because it is so much more lavish than Pan or Toad, and yet seems to register overall as less effective. I don't think anyone bemoans the few great animatronics it showcases, but for all the rest of the trouble they went to it feels like the ride comes up short. That jibes with the multiple retoolings it's undergone since opening at California Adventure four years ago, which have since been matched at WDW.
Someone mentioned in another thread recently that they believed Winnie the Pooh should perhaps have replaced Snow White instead of Mr. Toad, and went on to suggest that Toad probably would have turned into Mermaid then at a later date. Reading that, I couldn't help imagining Mermaid being translated into a ride that would fit that building; in the style of some of the older Fantasyland Dark Rides, blacklight cut-outs and all. It reminded me of this Emporium window display -- I feel like, with so much less, it does so much more to capture the feel of the movie than the ride actually does. Even with its expensive rock work and cheap fish-mobiles (Beautiful queue and Ursula animatronic not withstanding).
I guess what I wonder, then, is what would
Disney define as "far less lavish"? Fewer animatronics? Less interior rockwork? Because if it meant scaling back to a style closer to an Emporium window diorama, with all it's inexpensive magic, maybe that wouldn't be the worst thing. I'd love to see them producing more in this style.
