GMR being replaced by MMRR was definitely one of the dumbest ideas WDI's ever executed. Compared to GMR, MMRR has lower capacity, fits the park less, is shorter, and to top it all off seems to be cumulatively regarded as mediocre. What a wonderful way to waste, what, oh a couple hundred million dollars or so. Jesus, it's just baffling. Even if GMR had low guest scores, this wasn't the solution....like at all.
As an aside, I think TWDC's current refusal to maintain ride effects, show elements, AAs, etc. is absolutely disgusting. The amount of money they make and they still choose to actively reduce quality simply because they're big babies and don't want to spend money to actually keep attractions working properly. It's genuinely pathetic
