Agreed with everything you just said about Cabin. Right now my Top 3 are Evil Dead, AWIL, Cabin... may shuffle again as I reflect on the experiences. But Cabin I think is being overrated, the only sequence I feel they truly nailed was the "blackout room" and the first cube room with the Ballerina and Screw Guy. Everything else felt extremely manufactured, tame, lame... I rewatched the film last week after visiting, and I realized they didn't really do the Third Act justice at all. All of the characters chosen to be represented are extremely cheap and uninteresting given some of the options on display there...
(Basically - why do Cabin if you're gonna stick with clowns, witches and scarecrows? Why not showcase the weirder stuff you couldn't ordinarily do? Unicorns, mermen, banshees, Kevin, spiders, snakes, the works!)
