I think everyone has guilty pleasure movies and shows they watch. I doubt everyone who goes to watch the FF movies believe that they're well shot films with social commentary and good storytelling. it's definitely not my cup of tea, but for others it just boils down to "car go vroom vroom", and that's fine.
My issue with Supercharged isn't that the FF movies are bad, it's that the attraction itself isn't very good. It deserves something that doesn't feel as mailed in. Probably a stunt show similar to Bourne or a themed coaster or indoor coaster like Mummy. Taking shots at the FF franchise for consisting of bad films and using that as an excuse to not have it at the park isn't fair, considering a lot of the attractions we have at the park now aren't exactly based off of "good films". Universal has traded in a lot of good attractions based on classic films for more contemporary and popular titles, which I'm not really a fan of, but I understand why they have to due to limited space and wanting to keep people coming back.
I don't know what the GP consensus is on Supercharged, I personally don't know anyone who likes it, and I would rather see it gone sooner rather than later. I'm just glad it's part of the Tour and not a stand-alone attraction out here taking up space like it is in Orlando.
