I disagree. Yes, there are lighting issues with Mermaid and in all likelihood those will be addressed in the upcoming refurb. There is far more to The Little Mermaid than there is to Peter Pan's Flight. The blacklight simplifies the show scenes of Peter Pan's Flight whereas the lighting in Mermaid exposes the ceiling and other flaws.that ride is also in need of a dire update. But it works on a level that is better than The little mermaid. That much is certain. And that is for a ride that hasn't been updated since park opening.
Complaining that the animatronics in Mermaid are plasticy is ignorant if you don't also point out Peter Pan's Flight or Winnie the Pooh. IMO, Little Mermaid is a substantially better attraction than Peter Pan's Flight. Too many people are clouded by their nostalgia when it comes to Peter Pan's Flight. It is the most overrated attraction in all of Walt Disney World.
