I got goosebumps watching the thing on YouTube, so I dunno. It's certainly got me by the throat. Maybe these people don't connect with the properties? Which is fine, but that doesn't really mean the show isn't well put together.
Personally (key word), I'd put this above RoL and Fantasmic even without the pyro. I haven't seen HEA, so I can't comment. But the only Disney night show I'd watch over this is IllumiNations, and god knows what's going to happen to that next year.
But again, the OG World of Color was my favorite nighttime show ever, and this hits a lot of the same buttons for me.
