What he said. Behind closed doors that is the real reason for it.
We are a significantly softer society than we were in 1971. Even from 20 years ago. Everything is offensive. Most people don't get the charm of things like CBJ because they take it seriously. We have regressed as a society in so many ways since 1971 that it would need its own thread to discuss. Kids that are teenagers or in their early 20s I don't even want to imagine what our society is going to look like in 20 years. But one thing is for sure, people don't laugh anymore. Television isn't funny, late night television hasn't been funny in years and you'd have to dig deep to find funny movies or shows that come out these days. This is why the tongue in cheek attractions like CBJ don't "age" well in some people's minds. The whole idea of Blood on the Saddle and such is that it is intentionally meant to be funny. It isn't meant to be serious. I'm not very old, but even when I was a kid we knew this sort of stuff as kids, we didn't think the Bears were homicidal maniacs. This is why I cringe whenever even the suggestion of modern Disney "re-imagining" something comes up. Modern Disney couldn't re-imagine anything properly.
Probably the best laughs I had out in California was at the Golden Horseshoe. It was just pure slapstick comedy. Never taking itself seriously.
