I recently re-watched FRIENDS with my partner who had never seen it. I could see a lot of flaws, although my partner loved it. When I was a kid that was the number one show, and even the silly dramatic cliffhangers felt earth-shaking. It's pretty funny watching it now.

I am also watching Seinfeld for the first ever time. For some reason, it was never really "around" when I was growing up. Overall, I'm really enjoying it. It's lost some steam (im coming towards the end, I think), but no real complaints.

Other than that, I've only seen sporadic episodes of things like Frasier, Malcolm in the Middle, and Cheers, and like them well enough. Just not enough to fully watch and follow. I haven't seen any recent sitcoms that weren't utterly terrible.
