I've seen this theory a lot this week. Have we forgotten that Supercharged -- based on franchise whose average box office probably triples F&tF -- closes for months at a time because no one wants to ride it? Or go to the Tropical Americas thread, discussion today is how Dinosaur hasn't pulled in a crowd for years.
The idea that the GP has no taste is just flat-out wrong. There's always an early bump, but in the end, good rides will out. Word-of-mouth means the turkeys just don't draw a crowd long-term. (And if WDW CMs and influencers honored with the chance to be FIRST! on a new ride are meh on it, I have little faith people who dropped $200 to be there are going to be more forgiving.)
