I have little doubt that this will be a very good show, but do I think it will be as good as IllumiNations was? Currently, no, and for that there wasn't 5 giant LED screens parked full-time in the middle of the lagoon.
I'll give the show a fair chance and tbh, i'll probably enjoy it. It will have to be really freakin good for me to give a pass to those screens, though.
