Well, one certainly doesn't need to "appreciate" it if one finds a lot of problems with the entire concept (this does not mean that one has to completely down talk it or, more importantly, talk down people who like it), especially those of us who felt there was more to the Maelstrom/Spirit of Norway experience.
Beyond the problems I have concerning the overall theming of World Showcase being disrupted (along with the various issues others have been posting here concerning lack of cover and other logistical matters), I find the actual style of ride they put together pretty unimpressive. I've heard some say it would be a solid Fantasyland ride, and I'm not saying it would be bad or that it is bad, currently, but most of the classic Fantasyland dark rides based on IPs have focused on certain experiences tied into the films, not the plot content of the films themselves. The original Snow White ride focused on the scarier aspects of the film, Peter Pan focuses on the parts of the film that most highlight flying, Mr. Toad the madcap "mania" aspects, etc. This was by and large a byproduct of these rides being developed before the home video market, but it made sense, and falling back on "let's just tell the story of the movie" or "let's just play the songs from the movie in ride form" hurts re-rideability, as best I can tell, because would-be riders can simply go home and watch the film there to get a similar experience.
I know thinking these things won't change the ride back into a form I'd find more interesting, but, well, we're fans, and this is what we tend to do a lot.
