Looks like everyone nailed the dramas so I'll recommend some comedies. Trailer park boys, its always sunny in Philadelphia, and curb your enthusiasm are all great!

i think the ultimate marathon show is 24. see if you can watch a full season in one go (it actually takes less than 24 hours because each episode isn't an hour long when you take out the commercials).

i would also recommend: the wire, the shield, breaking bad, lost, friday night lights (if you want a good high school drama type of show), freaks and geeks (comedy).

band of brothers and the pacific are both epic war miniseries.

Season 2 of Girls will air on HBO in January 2013.

Very glad to see Freaks And Geeks get a mention here. I do an F&G marathon once a year.

Well, sort of. I don't tend to do a true marathon where you watch an entire season or series all in one sitting. It generally consists of three- or four-episode blocks per day (maybe more on a weekend) over the course of a week. So more like a TV Tour de France.

Speaking of all these running/cycling analogies, this TV-watching is a good thing to incorporate into the "Get Your Fatass Fit" thing if you have the resources (Link to thread). I watched almost all of the first four seasons of Mad Men on a portable Blu-Ray player while doing cardio workouts at the gym. I'm still not in great shape 'cause I eat like a teenager, but I'm far better off than I would be had I not gotten in those sessions.

Mind you, watching a TV show not a great thing if you're already somewhat fit and you're trying to really get into shape -- e.g. it's harder to complete the high-intensity portions of interval training when you're intently focused on a screen. But say you're just trying to build the discipline to get in an hour on an elliptical trainer four times a week -- you can really pass the time by knocking down three episodes of Arrested Development while churning out 11-minute miles.

The last 2 months I have blasted through the first 5 sesons of "Dexter." It's an awesome show. Well written and perfectly cast IMO.

Also, "Sons of Anarchy" is another pretty well written, well cast series to catch up on and still running.

On my list to start is "Mad Men," "Breaking Bad," and "The Wire." This is a great thread topic **Thumbs Up**

Will download. It's slated for after Game of Thrones S2, and will probably hold us over until all of Falling Skies Season 2 airs.

Also FALLING SKIES IS BACK!

Buffy the Vampire Slayer

+1 on 24.

Currently have The Wire and Breaking Bad at home, haven't watched yet.

Apparently Spartacus is good too.

The second time through is even better. Watching for the first time your focus is so much on the plot and the interweaving storylines that so many of the intricacies and subtleties are lost .Once you know the characters and what their motivations are, so much more of the genius of this series comes to light. I cannot recommend this show highly enough.

Breaking Bad
Homeland
Buffy

You're right, second time through was great. I re-watched it to show my wife starting the day after the series ended. Just did the same with Breaking Bad, except that it hasn't ended.

Homeland was great!

I'll add Louie - 26 episodes so far. Season 3 started last night.

Tier 1: The Wire, Breaking Bad, The Sopranos, Deadwood
Tier 2: Game of Thrones, Mad Men
Tier 3: Prison Break (Season 1 only! Season 2 maybe), Lost, 24

Honorable mention: The Simpsons. Cant go wrong with them, and theres enough material for 20 marathons.
