This might be somewhat of a controversial post, but Disney building family coasters sits better with me than Universal replacing a more teen/adult oriented pair of coasters with a family coaster. The reason being, I just see Universal as better off being the yin to Disney's yang. To me, you can't beat Disney at its own game, and I see Uni tearing down Dragons and replacing it with a family coaster as them trying to do just that. The thing that got me into Uni in the first place was the fact that they were an edgier, adult-oriented contrast to Disney. And I'd love to see them stay that way.
Again, JMO.
