Well we saw that Disney is still willing to create a show without any IPs attached (Rivers of Light), but it receiving mixed reactions has me worried about if they would be willing to risk creating another show without IP. Of course, DAK can't really use pyro much whereas Epcot goes crazy with it so that does make a difference in one aspect.Yes. It's certainly time for something fresh... but not something dumbed down for kids to more easily consume, which I'm almost certain is what the eventual new show is going to be: not a celebration of real culture, but a celebration of fictional characters.
If that's what it ends up being, hard pass from me.
But the more important aspect is storytelling. Rivers of light has very poor story-telling with a muddled plot and one of the worst climactic sequences i've ever seen in a nighttime show. And then it just ends.
