i don't know. those are the only types of shows i watch, actual episodic TV shows, where an ep is just a chapter, not some file in a larger story that could or could not be meaningless to the overall plot. those are the ones that are wildly popular and the reason why sitcoms are sinking fast and becoming even more generic just to capture that small populace that just wants to chill the fuck out and be slightly amused. while some are better than others, these are the shows i mean: 24, rescue me, the shield, deadwood, sopranos, and, up until it did become that stalling overburdened behemoth, Lost. Deadwood and the Shield are king among these shows, but they've all got that thing going that, well, i don't know if it was missing for awhile or not. Maybe it was there in 90210 or Melrose or something, but way dumbed down. The season-long story arc spread across 10-20 episodes. With Deadwood it's definitely more pronounced, as in, this arc isn't a general guideline, it is the major force in everyone's lives and they're all dealing with it and they don't get to escape via flashback to when they were blowing up their drunk stepdad's house or working at Cluck'n Bell with Road Trip Boy.
but anyway, onto the marathon question. i watched season one all in one day when i was sick. season 2 i watched over a week. it was great, but doing that, i think, leads to everything blurring together. it's a lot different when you wait a week in between each episode and let the antici....pation build up. with 24 it's a chore, because you know pretty much exactly what's going to happen next week, but you don't know what the last 5 minutes will be. you're suffering through some bullshit drama and a few cool action scenes not for a punchline but the next set-up. Deadwood though, you never know what's going to happen next, and when something does shake things up, it's never like, HERE'S WHERE THE TWIST GOES AND THAT'S WHERE WE'RE PUTTING IT AND WAIT FOR IT, WAIT FOR IT...BOOM. it just shakes you whenever it feels like it.
and it's all written in iambic pentameter, so.
