I think my biggest beef with Simpsons is that it's literally Back to the Future: The Ride but without Back to the Future. The theming, paint job, queue, pre-show, and such were just cheaply changed to Simpsons.
I understand BTTF was old, and I get that Universal's marketing really wanted Simpsons but this is not how you replace an attraction. It's just lazy and it REALLY shows. You're supposed to be in a theme park and it does not feel like that at all. You can't just slap cutouts and paint the building and call it a day. They could have at the very least tried to put tent props over the building so it looks at least something like a carnival/theme park.
The footage is just horrible in every way. Unlike Back to the Future, in The Simpsons Ride you "just so happen" to be behind the family the entire time. No matter how many times there are explosions and such and you're knocked away from the family you always "just so happen" to catch up. In reality once you fell off the coaster that would be it. At least in BTTF we were chasing Biff and were involved in a first person adventure. As soon as you stepped into the IFT you were part of the ride. The Simpsons doesn't do this at ALL. The ride building itself actually looks like a working building from the outside. As I mentioned, the carnival/theme park theming isn't there. It's lazy. The screen is also incredibly dark. Like REALLY dark. If you're going to have a simulator you have to simulate. Our world is a bright and colorful one. The Simpsons ride is dark and dull. It's not easy to get immersed in the ride at all.
The Simpsons is (in my opinion anyway) a bad attraction. BTTF bias aside I really expected the closure of such an iconic and popular attraction to at least have a good reason but it's not. It's cheap and obviously was made purely to sell merch.
Yes I understand that "it's spilt milk" and it never will come back but this ride alone is why I side more with Disney these days. Yes we shouldn't be stuck in the past but to forget your history is just as bad. It's a generational thing. When someone goes to Disneyland they can ride the same ride their parents/grandparents rode but at the same time they can ride brand new attractions. Look at Star Tours. Granted SW is immensely more popular than BTTF, but at least they took the original attraction and made it brand new.
I'm not attacking anyone who enjoys the ride or anything and in fact I'm glad you do, but from a riders, artist, filmmaker and fan perspective, it's lame and it's painful to know we're probably going to be stuck with it for another 10 years.
EDIT: To add to this really quick I just want to clarify these are just my thoughts and I don't mean to sound rude and such.
