The range of opinions on these boards stretches wider than the widest ocean. It's not a bad thing at all, and I love hearing people's thoughts. Some of the opinions people have are surprising though.
But I think the no-character fear is weak. Although my anology may not have been the best, there are so so so many things in WDW that have no "characters," aren't thrill rides, and yet are super popular.
Plus, the show is at night, and families of little children don't all stay that late. And if some families don't want to watch the show because their favorite zootopia fox isn't in it, they can miss out. It'll save room for everyone else.
Floating lanterns tho'
Sure, you may be joking, but my point to everyone is that, yes, fireworks are cool, but are they the only thing other than movie characters that get little children excited? Umm I don't think so. The lights and colors, the fountains, the floats and sloating lanterns, and the music should all get their attention and smiles. There should be enough visual flair in front of them to prevent boredom. And as for the message or theme, even though they don't "get it," that's okay. Their parents do. Therefore the show will cater to all viewers in different ways, something that doesn't always happen with newer shows and movies.
And as I've said, characters would ruin the theme and message of this show for your large percentage of guests who do "get it" (ya know, the paying folks). The show simply cannot be as captivating if it included characters, they have no place here. Especially for a show smack in the center of the park. It has non-movie-character animals in it. That's not all it needs, that's what it needs. I truly hope future changes don't "break down" what looks to be a good and captivating show.
