DHS and DAK would both be infinitely better parks if they had a few Fallons in their lineups. "Oops! All E-Ticket's" is a legitimate issue.
Rides can and should be a little bit bad sometimes. Fallon is not ground-breaking, exceedingly entertaining, or thematically interesting, but it does its' job as a competent fun indoor ride that I can count on riding in less than 20 minutes. Same with Transformers.
I'd argue that Simpsons, Minion Mayhem, Supercharged, and before it left, Shrek 4-D do that job substantially worse. The lack of variety on top of that leaves USF with a notable stink imo.
