Here's the thing though (and for the record, I'm not arguing that this is good or bad):
As much as we may not relate to it personally (and I do include myself in this, to an extent), it's pretty clear that they're moving in the direction they're moving because the bulk of park goers want it. I miss Maelstrom too, but three years in, Frozen Ever After can still get 2+ hour waits, and the lines at the Anna and Else meet 'n greet are frequently long as well. They ultimately want things that draw people into the park to pay for admission, merch, and food. IP-based rides are clearly good business. That doesn't mean it's aesthetically good, but it's an understandable decision from a business standpoint.
Personally, if they're going to use IP, I'd just prefer the rides they use it on be GOOD. I found Frozen Ever After to be technically impressive, but not exactly innovative, if for no other reason than they just re-skinned Maelstrom. I am not the target market for Frozen, so I can't judge the rest.
