The potter lands are in parks without real cohesive themes, they're just collections of IPs. You could argue the literature theme of Islands of Adventure, but that's fairly weak. Pandora's fit into Animal Kingdom's themes is more a function of how cohesive that park is than a criticism on the other parks. That doesn't mean Pandora is the best theme park land (personally, I still think Africa is a better land in the same park).I did mix up E and A tickets, you're correct. Care to explain why I'm "crazy"? The fact that I think WDW's strength is major dark rides and that it's been moving away from that for decades?
I've explained in the past why I don't find Avatar a particularly thrilling subject for a themed land, so I won't rehash it. I will agree that it fits thematically into AK. However, I don't agree that either of the Potter lands AREN'T thematically cohesive with their respective parks. Cars Land doesn't really fit in DCA, but I find it and the Potter areas much, much more compelling and complete than Avatar. That's a subjective opinion, of course.
