I'm rewatching the series in 2020 after having discovered it in a library almost a decade ago and WOW! Has it aged well! Or maybe it's just that the world has aged badly in intervening years.
Step into 30 Rock and inhabit a world where female wit is a force to be reckoned with; where every actor gets their 2.5 minutes of fame per episode, and every character brilliantly subverts their own stereotypes in a way that's deep but not at all serious. From the mid life crisis man in Adsit, to the self sabotaging female boss in Fey, to the rags to riches star in Morgan, the aging fame addicted starlet in Krakowski... you never get tired of seeing the layers fall away from these people. It's light, but still riveting. And it is all tied together by plot arcs that are as insane as the best SNL skits (and funnier, in many cases).
By far, though, the best thing about watching this after several years is that it is so packed with one liners and sharp, snide social commentary that you can watch it again and again and still see new angles and perspectives. There's almost too much to take in in one single viewing in any of these episodes - and that's a great thing if you're a fan of the series, which I am.
I have a feeling you will be, too.
