I'm not devoted to many these days (Thanks, reality TV, for doing that to television). But I do watch TNA Wrestling every week and try to watch Rescue Me every week. I usually watch Justified. I like to watch Family Guy when it comes on, but I only watch it on TBS, the CW, etc. I'm just not a Sunday television kind of guy. I don't watch The Cleveland Show, because its setting is a place called "Stoolbend, Virginia" and Family Guy was notorious for making fun of the South. I wouldn't be able to stand watching it if my beloved home state was mocked. Pff, L.A. writers. They act like they've never been outside of Hollywood.
Of course, my favorite TV show of all time was Digimon: Digital Monsters. But...at least I now have all of the episodes, so I can watch them at my leisure.
OH! And I also watch Smallville, though I started watching it only a few seasons ago. It keeps getting better and better.
