To start, I realize what I'm about to say is a pipe dream... But, it sticks with me.
My biggest disappointment with this is the opportunity a new build could have been. Leaving aside the co-op story, the more I see of this - the more I wish this would have been MK's Blue Bayou. Having Tiana's Palace with a large "patio" overlooking the "Mississippi" or "Lake Pontchartrain" as it wanders off into the Bayou. Then an attraction like this mirroring the scale of DL's Pirates. It could have been the ultimate animated film dark ride, given another must do restaurant and given MK the "answer" to Pirates people always mention when comparing to DL. And, the stories and themes would have been different enough to not feel repetitive, especially if it anchored a NOLA land or mini-land.
I realize Splash was viewed as having it's own problems with the source material. I just think this would have been a true showcase for what PatF and Tiana could be. And, it's tough to not feel the shoehorn with this redo for me.
