So, I haven't done this in a while. The last (actually, the only) time was after finishing Deadwood, and that list had only 14 shows on it. Over the past two years I've added 19 more shows and removed one (Arrested Development, due to its revival on Netflix), bringing the current total to 32.
For those who don't know, this is the constantly expanding, ranked list of every single show I have ever watched. Currently airing shows are added after they conclude their runs (so no Mad Men yet), although in some cases I may make an exception for a long-running show that I stopped watching before the end. I quit the U.S. version of The Office midway through season eight, for instance, but I felt like it should be represented here, so I put it on the list as "seasons 1-7" (meaning I didn't consider those largely mediocre season eight episodes when ranking it).
