Flugh. Okay. Strap in.
Breaking Bad - Probably the best show currently in production. About 70% drug-related suspense story to 30% dark comedy. AMC, first four seasons are in the bag, next season will be the last, broken into two parts, and start this summer. Con - you’re not really supposed to “like” many of the characters.
Justified - Close runner up for maybe the best show currently in production. Modern western set in Kentucky, on FX. First three seasons are in the can and it’s renewed for a fourth.
Louie - Easily the best half hour program, but maybe not the best half hour comedy. Caveat - it can be kind of a downer from time to time. Two seasons done on FX with a third coming up in the summer.
Archer - Easily the funniest comedy, though it is exceptionally jokey. Three seasons done on FX and a fourth coming up at some point (presumably Winter 2013).
Mad Men - Extremely high quality program - has the same likeability issue as Breaking Bad for some people. Soap opera in the truest sense of the word (there is absolutely no genre or procedural element to this show), but don’t read that as a bad thing. Four seasons in the bag from AMC with a fifth currently airing.
Game of Thrones - Extremely affecting, well done overall, but just brace yourself for remarkable amounts of callous brutality without any justice in the near term. Medieval sort of middle-fantasy (low in the first season, but it will steadily increase as it goes) on HBO with one season done and a second airing now.
American Horror Story - This is not a good show by any stretch of the imagination (the entire thing is basically turned up to 11), but it is audacious as hell and sort of ridiculously addictive. One season on FX with another coming this fall, and all of them are going to be closed, self-contained stories.
Bob’s Burgers - First season was pretty okay, but the second season has dialed into the parts of the show that were the funniest. Animated comedy in Fox’s Sunday block with one season done and the second airing now.
The Legend of Korra - See below; this recommendation gets complicated.
Community - Archer’s competition for best comedy. Slightly less jokey, much better assembled. Fuck them for making me cry during the Imaginarium episode, but, still, that’s some damn good programming. Two seasons done with a third airing right now on NBC and most of the gossip has a fourth likely at this point.
Homeland - Modern espionage thriller on Showtime. Much more excellent than I thought it would be going in. Tense, with some action. One season done, second one coming up later this year (presumably paired with Dexter again).
Venturing outside of what’s currently on the air…
Supernatural - Specifically, seasons 1 - 5. It’s not that it got bad after 5, but it was among the best on television that year. It’s still on the air, but I don’t think it’s ever going to hit the same high it did then. Genre show.
Terriers - One season, closes well, maybe my favorite show ever. Modern noir, from FX, and I think it’s on Netflix.
Avatar: The Last Airbender - There’s, like, one outfit that does all ages visual programming any more, and Pixar only does movies. That said, this show right here is just about as close to a perfect all ages show as you could hope for. The story is continued in the successor series Legend of Korra, but you should start here for the full context. Three seasons for Avatar and they’re in the middle of the first season of Korra on Nickelodeon.
Dexter - Season 1 and 2, specifically. A sort of genre-adjacent show about a serial killer who kills killers serially and maintains a normal life on the side. First two seasons were exceptional, but it started to slide after that. You could extend the recommendation out to 5 to catch the John Lithgow bit, but 6 was…entirely ridiculous.
I have a small army of stuff that I would recommend just under these ones, but they all have more significant conditions on them (i.e. Breakout Kings is good in an old television sort of way, Lost is good if you can live with a somewhat controversial ending, same for BSG, etc.).
