Slate has a fascinating article about TV critic Alan Sepinwall and the genre of immediate, in-depth episode-by-episode TV criticism that he pioneered and perfected.
I can't tell you how much I've enjoyed reading Sepinwall, Tim Goodman, Matt Zoller Seitz and all the TV Club people on all the great shows of recent years- there's nothing like watching an episode of "Mad Men" or "Justified" or even "Community," and then immediately go online and read 3 or 4 essays about them. I'm also working through "Breaking Bad" reruns, and every episode I've watched has been followed by reading Sepinwall's recaps.
