I partly agree with you but I think with regard to DCA it is more complicated. I thought the move to change Tower of Terror into Guardians of the Galaxy was absolutely terrible. What I have heard is that Disney had a licensing issue with the Twilight Zone IP owner which made changing ToT a priority for them. For some reason DHS either does not have the same issue regarding ToT or the timing is further out in the future. I do not know. I think that is what pushed them from ToT to GOTG at DCA. To their credit, they did a good job with GOTG and it has been a huge hit with visitors. Whether it has along a long shelf life is TBD.
Just about everything else that they have done to DCA has been A+ to me. Except for changing the theme of Condor Flats to more of a National parks theme. But I was clearly in the minority on that.
Now they are changing Paradise Pier to Pixar Pier. In that I thought Paradise Pier was a weak, cheap theme in the first place that would make Walt Disney roll over in his grave (he did not like seaside amusement parks which is one reason he built
Disneyland in the first place) I support the transformation of Pixar Pier.
However, I am concerned with GOTG and Pixar Pier they are losing touch with the theme of the whole park as it relates to California.
With regard to DHS, it sounds like I liked the DHS of recent years a lot more than the typical WDW visitor where it ranks #4 in visitors. I am sad by how much they are changing it and afraid it will not feel the same anymore. Star Wars Land? Perfect move. Toy Story Land? Not sure yet. Closing Great Movie Ride for Mickey Mouse ride? That will make me forever sad. Although GMR was showing its age and probably becoming less and less relevant to the younger generation. Loss of Lights, Motor, Action? I thought that was perfect for DHS and am saddened by that loss as well. Streets of America? Good riddance to that waste of space in my book.
