Isherwood shouldn't scare anyone. It's the only pan for a production that (unlike every other JCS in history) has otherwise met with love letters from every single critic its path has crossed. I don't see why, having seen and (cough) heard (cough) enough of the production to view it as another ubiquitous revival. But it's what's in.
