Oh no! How disappointing!
Well, maybe with time they get better and can re-visit it again!
I feel like at this point, Universal really only has Warner to rely on, Disney is owning everything else that has good enough IPs for attractions. Six Flags already uses Looney Tunes, DC Comics and Hannah Barbara (not really sure on that last one) so in terms of IPs, there isn't much to use. I was hoping for a Treehouse of Horror from The Simpsons for HHN but I don't know how this whole Fox in Universal Parks is going to fly now.
