I personally don't really see a step down in quality from Potter to Kong to Fallon. The fit and finish to Fallons queue, particularly in the downstairs lobby is actually really well done. Everyone keeps saying the theatre isn't themed at all which is not true. The red seats with the blonde wood accents looks like the theater in Rockefeller Center, there are blonde wood panels on the wall and the studio light rig. I love the folks who are all, "OMG, look at that light rig, that's worse than the little mermaid ride". It's a movie, no light rig necessary. It's called detail to reinforce the theme. Or as us geeks call it, "THEMING!"
I get that everyone hates Jimmy, and it's a silly piece of fluff, and everyone is tired of 3D, but the ride is well done for a D Ticket and has really high GSATS. I don't really get the hate. I'd ride Fallon all day over NRJ.
And I really like Kong. More than Gringott's. But it really sticks to the gringott's formula. Massive facade, great queue, wonky storytelling, start and stop in front of big screens, and an anticlimactic climax.
I walked out of Flight of Passage kinda meh because I loathe the IP.
