Honestly, FEA was the vibe I got from it, and that's not a good thing. FEA sells us on the idea that "we've" been invited to Elsa's castle and...no? No, "we" haven't? It sounds like such an obvious thing to point out, because, duh, we don't personally know a bunch of fictional characters, but it completely alters the dynamic of the attraction to have characters talking to us like we got on this ride because we are actively trying to keep an appointment with someone, rather than because we are simply interested in exploring what this ride contains.
I said it in the other thread, but it'd be one thing if it was a story like in Dinosaur or Spider-man over in IoA: in those, we're technically part of the story, but again our role is a passive one: Spider-man warns us we're making a mistake following him on such a dangerous night and ends up bailing us out, no help from us, and in Dinosaur it's Seeker roping us into his scheme, not us actively "helping" him. An even more direct example of when this works is when you have a shooting gallery right; at least in those instances, the riders ARE playing an active role.
Instead, this, FEA, Cosmic Rewind, et. al. are acting like we've gone out of our way to sign up for some kind of activity or are being enlisted to do something significant, but then they place us in a ride where we just sit there and things happen around us; we play no active role, but the narrative is telling us we did. It's a very, very strange dynamic and disconnect.
But yeah, the lack of build up is something I can't begin to comprehend; one of my personal traditions sometimes in the WDW Splash was to bang on the rubber surface in front of me like a war drum, because as you climb to the top you're supposed to be getting a feeling of "oh crap, here it comes!", which makes you want to scream that much louder on the big drop, which in turn makes you that much more giddy when you splash down and then celebrate in the final room. Turning it into a good guy character just saying "Oh, here, let me get you to the party, have fun!" before the drop is like, I dunno, turning Tower of Terror into a wacky cartoon gag with an elevator that goes up and down at random, maybe? I don't know, I'm having a hard time thinking of an equivalent, because it runs so counter to just about any instinct I'd have about ride storytelling.
