I'm not sure how much an unpopular opinion this is, but here goes: I hated Simpsons when I rode it. I don't get motion sickness, ever. However, this ride made me feel sick in a totally different way. The smell, was the main thing. I specifically won't ride it again because it cannot hold a candle to BTTF in my estimation. The ride vehicle isn't enjoyable, the positioning of the vehicle seems to be off with the screen too. I can't quite put my finger on it, but something just didn't seem well put together about it. Maybe it is my high opinion of BTTF because I am such a fan of the franchise, but the two are chalk and cheese and I know what I would rather eat.
Jaws I can take. I loved it, despite it giving me deep seated fear of water when I was a child. That ride literally ruined swimming pools for me for a couple of years. However, if I could go back and ride it again, I would love to do so. However, Diagon Alley is spectacular. Jaws made way for something better. In that frame of mind, I do think ET would make way for something excellent too when it does eventually go. I'm glad it is sticking around for longer though, it's nice to still have something left over from the old school.
