If any of use here, (and keep in mind we are all Disney nerds) were in a test group and we watched this show without any information about what it is for, and after watching it were then asked, "what is this show about "? We would not answer, "50 years of Disney". We wouldn't even say, "Anniversary".
This show should OOOOZE 50 years of Walt Disney World. The music and scenery from the attractions, resorts, characters, etc should rain down upon you. The nostalgia of the old all the way up to the love and excitement for what's recent should be represented.....but it's not.
This show should have been a quick special on the Disney Chanel or ABC. Not a representation of 50 years of Walt Disney World, because it's anything but.
