For comedy: Curb Your Enthusiasm, Louie... occasional cartoons (family guy, etc. ...no, I am not a Brony). Daily show.
I've seen nearly every L&O in existence, though the show just doesn't seem the same without Orbach. I like the CI's with D'onofrio (though I prefer the original -- Columbo), but the writing went downhill fast when he took a break.
I really tried to like CSI. I watched the premier and was just so baffled when a crime-scene guy made the arrest! When I tried watching it again recently I just couldn't stop wondering why they never turn the lights on.
The Office is solid, but since I had watched the original one first I haven't felt the need to watch the new one. Same with Wilfred. And Shameless (though I'm a big Macy fan). And Being Human.
Dexter is good.
I wish I got the Torchwood channel. I heard Bill Pullman is in it, and I think he is an underrated actor.
