I actually think MMRR is *better* than GMR though I would have preferred they kept both. We will see about GotG. UoE was an embarrassment during the 2010s.
Frozen singalong is surprisingly good and better than anything in that space in decades.
Toy Story Land is more enjoyable than any recent Backlot Tour.
Soarin Around the World is a net-plus for the park—we got digital projectors and a show that fits Epcot better.
The new Land show is actually good. Haven’t seen the Canada show or BatB singalong though I expect the former is good.
I liked the M:S updates.
The Coronado Springs update was absolutely a win. And I personally approve of the Copper Creek updates at WL.
It hasn’t been that awful...
MMRR - haven't ridden yet. For now, like you, I shall stick with the both appreciative and damning thought of 'finally a fun Mickey ride, shame about it replacing a headliner instead of being an addition as in DCA'
Frozen singalong - toddler theatre is not what I dreamed WDW would replace itself with.
TSL - awful. The aesthetics of a cheap regional knock-off park, with mediocre rides. I liked this area better when it was a water tower.
Soarin' CGI Adventures - mixed, indeed. Better fit, lesser ride. Contrary to TT, for me final verdict is a slight loss. Personal taste may vary. (But with modern digital technology, couldn't they have added a few randomised destinations? )
The 3 new EPCOT movies I haven't seen yet. In principle movies should be replaced every now and then, so a priori an improvement. Is the new China movie as good as the previous beautiful poetry of image, word and sound of Li Bai and that wonderful soundtrack? Here's hoping! Props though for three movies that don't revolve around princesses, an astonishing accomplishment by somebody still caring, somewhere!
M:S is awesome and only got better. Touchdown for the Butler.
CS lost much charm to me. Although as so often, years of neglect and under investment almost make any redo a net plus. The story of most of WDW.
