Probably best to lower expectations and be surprised later on.
They haven't even started on significant construction yet, so the turnaround to get this is ridicously short. My worry is that this will be similar to The Seas with Nemo and Friends which is essentially just Coral Reef props mixed with screens. Works for Nemo since the characters are recognizable, but not sure it can work for a non-IP based experience.
I wonder why they didn't go with something Sesame Street.
