Which could be good, or it could be bad. The good part might be that Disney will look at the results of Mermaid and try a lot harder to create a truly amazing immersive experience the next time it builds a dark ride. The bad part would be if Disney decided that building new dark rides wouldn't be worth it, and point to the Mermaid ride as an example.
Really, Disney has got to try harder. I remember the first time I rode the Nemo ride at Epcot. It had been hyped up bigtime in the press releases and on TV. But when I rode it...holy underwhelming, Batman! The screens look just like that - screens, with cartoon fish projected on them. Not ONCE did I get the feeling I was underwater, or that Dory and Nemo were really there. It was LAME! It felt so cynical, as if TDO believed that the affection guests feel for Nemo would overcome the mediocrity of the ride. Um, wrong!
