Perhaps Disney is correct to not pursue a Beastly-land at Animal Kingdom. I am afraid that Disney is out of ideas. They can't seem to pull off a great concept because they are exactly blue skies. They aren't meant to be built.
I would also love a Stephen King themed attraction as well, but again as Sylvain stated, it would be best for maybe HHNs.
That's something I think Universal needs to do more of...making things that are not for kids in its parks. Disney can't ever do that, because Walt Disney's personal philosophy was that the parks should have attractions that everyone in the family can go on and enjoy...so Disney can't ever be intense, gory, and truly scary.
Universal doesn't have to tie its hands like this, though. Imagine a Haunted Library instead of a Haunted Mansion...and have it be a place where Stephen King's books come to life. There are a lot of great scenes in his vast collection, especially in his short stories.
There's one story of his that would make an amazing ride all by itself...it's my absolute favorite. It's called "The Shortcut" (or something like that) and it's about a woman who is obsessed with finding shortcuts between the town she lives in and this one city. And she starts finding these access points onto "Motorway B", where she ends up driving in some alternate universe filled with monsters. That could make a spooky theme park ride...and also maybe the car could end up taking turns through all the other King stories.
Why can't a theme park have a truly scary ride that is just for adults? I'd really love it if Universal went in this direction and had a 21 and over land in one of its parks. Take the Pleasure Island idea from Disney, since they clearly won't ever do that again...and create some awesomely themed attractions and areas that are not in the least bit for children.
I have two sons and on every trip I think it would be nice to hire a babysitter for a few hours and have some alone time with my husband riding rides that are not saccharine sweet and for the kiddies.
