No, in your opinion most of the new stuff "isn't very good". To me, Simpsons is better in every facet compared to BTTF, Springfield is one of my favorite places in an Orlando theme park, Fallon is no more/less forgettable than the other two attractions that inhabited its space, Minions is a great ride, and Transformers is one of the best rides in Orlando. Not to mention Kong is one of my favorites in Orlando, and Hogsmeade and Diagon are two of the best lands in the world.
The only ride that is a downgrade, IMO, is F&F, even if its badness is way overhyped.
