Finding Nemo is beyond terrible, which is a shame as the sound track is exceptional, but the implementation of the show is so poorly executed.
Finding Nemo, the clicking of the puppets is beyond distracting and the show is overall boring, but I will give them that they are at least singing live, unlike Beauty and the Beast, more on that in minute.
Now in all fairness, I live in California and visit
Disneyland frequently where the entire cast of the shows sing and have mics. One of my biggest disappointments with Beauty and the Beast was seeing that so many of the performers were simply.lip syncing, including Belle and a couple of others. I know because there were points where their mouths weren't moving, but we could still here then singing and it wasn't some strange ventriloquist act.
Fantasmic! At Disney World is another one that needs some serious help.
