You guys will probably want to skin me for saying this, but I like Nip/Tuck, too. Last season it was God awful -- I couldn't watch it because it got too out of control and didn't have very good writing going on... But this season it is very much a return to form -- there are still those over-the-top elements that Nip/Tuck consists of, but it is more refined and the situations lend themselves to the growth of the characters instead of being included in the show for shock value. Right now, there's a lot of great stuff going on with the primary cast and if you watched it when it was first on I bet you would like it now.
Always Sunny is alright, although I prefer something like Curb Your Enthusiasm or the Office for random humor. I've never seen Sons of Anarchy, but I intend on watching it from season 1 when I get a chance. The commercials always make me want to watch.
