After reading a lot of the responses here in regards to overall satisfaction and location, there are a lot of things to consider. Initially I said this ride "exceeded my expectations," simply because there are AA figures and not just screens. Honestly I thought the ride would be mostly screens of the characters seeing as how gran fiesta is next door and Nemo. So seeing the AAs pleasently surprised me and exceeded my previous expectations. Also I didn't know they were adding more ride space, I thought the original maelstrom layout would be the new layout. I couldn't help but think how upset people would be after standing in line for so long for such a short ride, but with the small addition they made to the layout, I think people will be ok length wise. When you think about it, people line up for hours for some of the most popular roller coasters in other parks. Coaster that are 30 seconds, 1 minute, maybe 2 minutes top. Of course people generally expect a roller coaster to be shorter than a dark ride, but if people willingly wait that long for them, can't blame them for waiting for a dark ride, not to mention a FROZEN dark ride.
With all of that mentioned and out of the way, the obvious two things that have been discussed in this thread before have to mentioned again. It doesn't fit in Epcot, and the fact that it was shoehorned in to a location that has horrible capacity is a huge problem. Epcot needed something to bring more people to that area of the park, but it needed something that would bring more people to that area of the park to check the new ride out as well as riding and seeing other things. Isn't gran fiesta still just a 5 minute wait? People aren't going over there and doing anything else but Frozen. And it looks as if when the line is too long they would just venture back to future world. If they had updated maelstrom enough to spike it's popularity to a manageable 30 or 45 minute wait, maybe other areas would see some foot traffic too. But people are going back there just for Frozen, which makes sense because it's so popular. But I doubt they would stay in WS after waiting 5 or more hours for one ride. They're gonna want to do the popular future world attractions.
Another big problem with the location other then what was talked about above, is the fact that the blueprint for maelstrom was something they couldn't get away from. The short backwards portion made more sense in maelstrom, but makes no sense in Frozen. It was mostly empty with little to look at(except the polar bear) but it didn't really need a lot to look at. With frozen the first part works, seeing Elsa in her castle singing and flinging her hands works, but the backwards portion is too barren with not enough to look at. It's not much they could have done in this space, but overall this part cheapens the entire attraction.
If it were possible for them to have kept maelstrom and placed this ride either way in the back of Norway, or have built an entire new subland in fantasyland, it would have worked much better. The MK doesn't really need a popular attraction like frozen as it's attendance is always through the roof, so I understand their reason for sticking it in Epcot. But if Dumbo could have stayed where it was before new fantasyland and they built an entire Arendale land that totally immersed you like cars land and with a ride that could handle the capacity and 300 minute waits without being too noticeable elsewhere, then we would have a much better solution.
So in all I understand people's gripe when it comes to location. It's not so much that it's in Epcot, but more so because it was built in a space that not only couldn't properly handle the crowds, but also couldn't be as good as it should. The backwards portion couldn't be erased and it's the worse part of the new ride. So like another poster said, it's whats right and whats wrong with current Disney.
