I do not like your attitude as much as you do not like Spirit's. And I diagree with many of your opinions, and perhaps I should not be jumping into this, but I want to at least try to explain why what you said here is so off. You are asking for an explanation and I shall give you one.
Frozen is a very popular movie, no doubt. There's absolutely nothing wrong with building an attraction around it. However, it's in the wrong place. The movie doesn't explore any Norwegian history, tales, myths, culture, or really anything at all. Other than the ice chopping dudes and maybe the trolls. And the fact that Norway can be very cold. But for the small amount of Norwegian culture that's in the movie, there is an equal or greater amount of detracting factors, such as the marshmallow monster and talking snowman, which add to the movie but are certainly not Norwegian inspired. The movie takes place in a fictional country called Arendelle, but even regardless of that, the Norwegianness is very light.
But the real problem, the crux of the issue, is that the storyline has nothing to do with Norway. It is of a conflict of emotions between two sisters and a town, something that could've taken place in America or Mexico or Australia or you name it. While the setting and characters have some Norwegian inspiration, the story does not. I'd be fine if the Frozen ride will focus on or do anything to explore the country of the pavillion in which it is housed. However, it looks like it'll just be non-Norwegian inspired songs with a few vaguely Norwegian inspired characters and settings.
I'm not completely against movies and characters in the parks, even in Epcot. They just have to make sense it that location. For example, Inside Out would make an excellent Epcot ride. The movie is about the brain and emotions, a theme/topic that fits very well with the whole idea of future world. It would fit well because of the story. Not because it happens to be a very colorful movie, and some pavilions are colorful too. That is the difference.
