I'd like to say, now that I've experienced Frozen in Norway, that one thing that wasn't much discussed in the thousands of pages of discussion on that ride was how the transition was handled. Seeing it in person, the attraction had little effect on the outer pavilion as a whole, even with the exterior changes that were made. Sure the cave wasn't opened, but I don't think you'd know something was missing if you hadn't already seen it before. The much maligned "flat" roof looked fine in person. There is nothing "toon" about the exterior. The sign is bolder, but not unreasonable. The first area is also treated realistically (and much improved over the old blue halls) with a bit of signage that starts giving you the feel of the movie. The very-well done plaza area takes you deeper into the look of the movie, but still keeps a foot in reality. Even on the boat, you're not fully there yet until you meet Olaf. So while the ride did little to tie together the film's Norwegian roots, I can say the experience at least isn't jarring in how you transition from World Showcase to Arendelle. Upon departure the transition still works, as you re-enter the plaza, then move back into the real world. Even the giftshop hits you with Frozen first, but blends back to authentic souvenirs and treats before letting you back into the pavilion proper.
In short, while I'll agree about the lack of edutainment value (though this does exist to some extent in the Stave Church exhibit) I will say I found the ride to fit harmoniously within the park. I'll also add that the largest audible and collective "Ooooh!" heard during our entire trip was from that first Olaf scene- absolutely phenomenal. There was also a woman on our boat (but not in our party) who refused to believe that the Elsa was anything but a real girl with a mask on.
