I tend to prefer the ensemble comedies, those without a big star when they were first cast. I guess from the mid-late '60s, Hogan's Heroes, The Beverly Hillbillies (though Buddy Ebsen was a decently known star at the time). From the '70s, The Bob Newhart Show (Newhart was a star, but hadn't had many acting roles), Taxi, WKRP, Night Court, Cheers, and Barney Miller (which is underappreciated). Later on, Newhart, Married With Children, Frasier. I've never seen a full episode of Seinfeld. When it first became a regular series, I was taking classes at night and hadn't seem more than a couple of minutes of it, and I had started working a new job, which was filled with many irritating people who went on and on about nothing -- just whined and complained all day. I didn't need another half hour of that after a full day of work.
Currently, I tend to watch things more in reruns than new. Big Bang -- I don't think it's as good as it was when the guys were all lonely and depressed, though I guess the writers couldn't mine that for a decade. Mom isn't bad, neither is The Goldbergs -- I enjoy the old video from the real Goldbergs from 30 years ago at the end of the show and how they work some of these non-actors into cameos. The Middle is OK. Modern Family has its moments, but I'm often disappointed in it, like it could have been better. How I Met Your Mother was fun, though the whole premise is a bit of a stretch. When The Office reruns are on when I can catch them, I'll try to watch -- I've only seen snippets over the years. Home Improvement and Last Man Standing were pretty similar shows, and both were pretty good -- I think Last Man Standing is the better of the two.
