Once Friends ended, I was knee deep in kids and selling my soul to the practice of law. I picked up How I Met Your Mother and The Big Bang Theory around the same time (TBBT when it started, and HIMYM a few years into its run). I watched those to their conclusions. I watched the pilot of Young Sheldon and thought it sucked, but I gave the show another chance a few years ago and have stayed with it through the end (which will be this Thursday). Along the way, I picked up Brooklyn 99, The Good Place, Modern Family, and, most recently, Ghosts (although I didn't think much of the recently concluded season). B99, TGP and Modern Family had all completed their runs when I started watching.
I liked the early Big Bang Theory, but it's on every night after the local news and I am beholden to the local weatherwoman, so I'm always watching that. I saw the steady and continual decline of that show years before the end. I am fully convinced that no sitcom should go more than four years. Seinfeld the obvious exception). EVERY sitcom, even the great ones, ALWAYS soften their characters to a point they are generic and uninspiring to me. M*A*S*H is another; it was brash, sarcastic and satiric in the early years, and especially with BJ, it became "heart-warming". Blech. I am in the Larry David camp; I don't want "growth", I don't want "lessons". No learning. I'm not interested in the actors "bringing themselves" to the roles. Sheldon in Year One was glorious. He was an obnoxious douche in the end. Trapper, Blake, Frank Burns and the early Klinger were awesome. Potter, Winchester, the later Klinger and especially BJ were nausea-inducing. I have a standing objection to children in sitcoms, so I boycotted Young Sheldon from day one, and when it replaced TBBT after the news I inadvertently watched a couple episodes and bolstered my commitment to boycotting children actors. That kid - granted it was the character too - was annoying beyond belief, and there was nothing funny about it to me.
