I feel like SeaWorld has finally and officially gotten over their Blackfish issues.
Now they have to deal with a rapidly changing theme park landscape that they don't have the cash or the IPs to compete in.
Sesame Street is going to be a huge boon for them. I think we'll see Universal beef up Seuss Landing as a response to Sesame Street opening up (wishful thinking, I know). It'll have a Potter-sized impact, but on a Seaworld scale.
