As I've said before, I dislike IPs. When I visit Alton Towers I want to see Alton Towers, not some random things from the media. If they were to come up with an original theme, I would love it whatever it was, but IPs (although they're a crowd puller and are great for business) take away a bit of the uniqueness and magic from the park for me. It does appear the Gangsta Granny ride is happening, but I certainly hope it's just that one ride, not a second area covered by an IP.
However the great thing about CBeebies and Walliams as IPs is that they are the biggest you can get. CBeebies just is British children's television, nothing comes before it. And David Walliams (discounting Roald Dahl who's not so current anymore) is number 1 in British children's literature. So as much as I would prefer an original theme by a long long way, I understand why IPs are a thing and to be fair these are the best out there.
Life is a roller coaster. You can either scream every time you hit a bump or you can throw your hands up in the air and enjoy it.
