I was surfing around the other day and found the TV Guide website. It has some blogs on the home page. These are mainly show recaps so if you miss an episode you can read about it. Not as good - but sometimes life is too short to watch online. Or on ITunes.
It's kinda sad that I've missed the last few Gilmore Girls. The writing on this show is (generally) wonderful and it's worth it to laugh at the pop culture references. But the story has gotten out of control lately (with Chris, without Chris, without Luke, with Logan, etc.) and it just isn't as good as it used to be. These may be the final episodes - we may have to buy the DVD.
