I agree. The series is kinda like M*A*S*H at this point. It's still running, but the paint is wearing off, the engine's starting to misfire, and we're getting to the point where we've gotten about all the mileage we can reasonably expect.
Grandma started watching Young Sheldon. I was dubious, but I've been surprised at the quality of the writing. The "crisis of faith" one was particularly touching.
Wish list for the BBT finale:
Everybody living, everybody happy. (My needs are simple and few.)
