Now, considering I haven’t been on F&F, I’d argue it suffers from three main things:
1) Poor narrative - This both is and isn’t Creative’s fault. Its narrative works as part of a larger attraction, where “invited to a party but our bus is attacked“ works as a fun sidetrack of a larger story (the tram ride), but doesn’t work as the narrative crux of an attraction by itself. “Something goes wrong,” is a bit of a meme now, but it actually works as a narrative device when it’s pulling from a purpose the guests are invested in (training to become MIB agents, retrieve something, tour something). F&F never presents something to be invested in, nor is there an reward. The story is a bombastic “is.” Creative’s failure was not developing a story that works for a standalone attraction. Their forgiveness comes from the directive that it wouldn’t be strictly standalone.
2) Poor production of the ride film - There are so many complaints about an oversized Vin Diesel, plastic looking skin, and indecipherable chaos in the 360 tunnel. That’s poor direction and film production at multiple levels. Creative can’t help bad acting. It’s also something they intended to do. Bad movies aren’t made on purpose; they happen when the countless parts that entail their creature, for one reason or another, just don’t jive. Even if the narrative was amazing, an unfortunately bad production will ruin it. Things didn’t click right with Supercharged.
3) Expectation of “Scale” - Earthquake wasn’t an E ticket. Neither was Disaster. They were bother pretty solid D tickets sitting between Es (Kong/Mummy and Jaws/Gringotts). Reign of Kong is a D ticket too. In a similar fashion, Supercharged is a D ticket. And, based on the decisions Creative and the park itself made, it was never going to be anything more than a D ticket. The problem is a lot of people expected F&F to be an E ticket. Part of that is Universal’s fault. Its a huge franchise filled with speed and thrills. It deserves an E ticket that provides that. But Universal decided to replace a D ticket with a D ticket, which is a decision that makes completely reasonable sense. But, I think, Becca they knew what they were creating and why (D for D), it was easy to lose perspective on most people expecting something more.
