Aside: some people criticize Fringe for being a remake of The X-Files, and my response is always, yes, but that's what I like about it! They took the same setup and the lessons they learned from the original and made a similar show that's even better.
Gray Matters is a much more arc-tacular episode, and is another one that made me say "Oh, Walter, what did you DO? I really love how complicated and ambiguous they're willing to make things on this show.
I have started enjoying reading reviews of the shows that I'm watching. The Onion AV club has a bunch of good ones, especially some older shows, but I'm also following along with Mark Watches, and particularly enjoying vicariously re-watching Avatar: The Last Airbender. Can't wait to read the reviews of the finale!
I never watch TV in realtime anymore (among other things, I have completely lost my ability to put up with commercial interruptions), and watercooler conversations about what was on last night are going extinct anyway, but it's nice to have persistent blog discussions about shows to spur the thinky thoughts after watching.
