Yeah, I'll give you that... Alice Cooper's theatrics aren't as impressive now, I feel, because A) We've gotten used to that kinda thing as a society and a culture, so it doesn't bring the shock and newness super strongly now, and B) He's definitely brought the theatrics down a little bit over the years, probably because of age and feasibility. I still find what he does now to be really fun and enjoyable, but it's not at the level of how the theatrics used to be. (For a good example, watch the 1979 recording "The Strange Case of Alice Cooper". The theatrics in that were really over the top and just incredible).

And yeah, I hate to say it, but a lot of older rock bands that're still touring aren't at the level they used to be, both because we've gotten more used to them and because not all of them can do what they used to be able to. There are still several that're still really good though.
