I'm going to precursor what I'm going to say with this... I am a huge fan of the original Epcot Center and an advocate for the original idea. However, times change. Attitudes change. Guests change. Therefore, parks need to change. I wholeheartedly believe that if Epcot were to open today in 2015 as it did in the 80's, it would not be popular at all. Can you imagine what the millenials would think of a theme park wher they had to learn?! The horror! Again, having said that, I'm not sure that changing Epcot's entire identity to an IP-centric park is the right path either. All I know is, I love Epcot. It's my favorite park. It alway has been my favorite park, and it needs LOTS of TLC. Do I think Frozen is a good fit for Norway? Meh. I think I'll be upset if the ride sucks. If they do a nice job, and it's a "plus" over the Maelstrom, then I'll be happy. I don't think that the addition of this ride marks the end of Epcot's vision. I do however think it means that Epcot is changing, and it might not be for the worse.
It just gets enormously tiring to come on the forums day after day and read the same complaints about Disney losing original visions and WDW doesn't do anything worthwhile any longer. We get it, things are different now, and we want them to go back to the way they were. Will they? Who knows. I just don't know why we can't be kinda, sorta excited that Disney is taking a (tired) ride that was left largely untouched or changed in decades, and turning it into something people actually want to ride. It may be like trying to shove a square peg into a circular hole to make it "fit" thematically, but I'm in the mindset that at least they're doing SOMETHING. Epcot will never be what it once was. So if it takes some IP's to get some fresh rides and fill the empty buildings, I'm sorry, but my nostalgia can take a back seat.
