How many total LANDS in WDW revolve around any of those movies? Heck, how many LANDS in WDW revolve around ANY movie? Zero. To suddenly have an entire LAND spring up around one not-so-great-but-good-looking-and-getting-old movie is simply strange.
As for wasting money, I was referring to the billions spent on
MDE/MB/FP+ rather than actually creating new rides. Disney is good at spending money to give people things they never asked for. Avatarland seems like one of them.
I'm not saying it will be horrible. I'm not saying I'm going to boycott it. I'm answering the question, "Was Avatarland really the best idea?". No, no it was not.
