Simpsons needs a HUGE refurbishment. Update the hydraulics, update the projectors to 4K per projector (there are 4 of them per screen), clean up the queue and add more details to the "outdoor" part of the queue (before the preshow) to make it look more different than the Institute of Future Technology. Right now, the dusty 1993 era air vents and architecture is unbelievably apparent, bur slapped with more color. Despicable Me did a better job of getting rid of the look of its previous "tenant". I really wish they'd cover the Dome screens better. Right now it's two big boxes with Krusty in the middle and some cut outs on top.
However, I prefer the giant size of the Omnimax screen than DM's high quality 3D. Cuz Simpsons RIDE experience is more immersive. It's immersive with DM if you have the perfect seat towards the front. It's more of a hit or miss than Simpsons.
Although I prefer the themeing, characters and story of DM.
