Agree with most of your points; the mine has never looked better, and the dungeon and the new projection mapping by the cauldron there are all great touches. It would've been so much better if instead of the mirror they had Snow's hand let go of the apple and roll it towards the path of the ride vehicle - less is more there. I don't think it ended too fast; I'm a sucker for the classic choral endings so this was right up my alley, and the lighting for the kiss was drop dead gorgeous.
Love me those classic choral Golden era animation endings. I’m glad they snuck one into the end of MMRR.
