I loved Will and Grace during its original run when I was younger. When I tried to watch it again as an adult, I hated it. Will, Grace, Karen, and Jack are all assholes who constantly punch down. I can live with unlikable protagonists with asshole tendencies, but I can't do punching down.
I will also watch reruns of ELR. There's something about that show that reflects real life and makes it funnier. There are a few duds every season, but when the show gets it right, it's still hilarious no matter how many times I see that particular episode
