The house that Johnny built is just about ready for the demo ball.
I’ll tell you the real problem that goes far beyond Jay and Conan... it’s the guests. The celebrities themselves have become less and less interesting (and less talented and well-overrated) over the years, most of them have nothing to offer and are often mindless morons and it’s just painful to watch (and that’s BEFORE you even get to what passes for “musical talent” today, which is beyond execrable).
If you ever see an old “Best of Carson”, even their worst shows featured guests you didn’t mind seeing, the “Old Hollywood” types. Most of those folks are almost all dead now, or long since retired. About the only one left worth watching is Don Rickles. His interactions with Carson were classic (remember when Don broke Johnny’s cigarette case and Johnny crashed Rickles’s set ?). There’s just almost nothing on these talk shows today that rises to that level of talent and entertainment.
