I'm a huge fan of the This American Life podcast/radio show, but I'll admit I was a little skeptical of this TV series since part of why I enjoy that so much is that I'm free to imagine most of the visual details, and that process is rather satisfying.
Netflix has the first two seasons available on demand, and in a bout of insomnia last night I made it through all 6 episodes in season one. It's not without its flaws, but in all, I love the television translation of this show. The production value is quite high, the segment length is perfect, and the stories are fascinating.
They have successfully managed to translate the idea of storytelling from aural to visual in a way that still inspires my imagination. The cinematography is often lovely, which is rare in anything that passes for a documentary.
My favorites were episodes 1 and 6, for entirely different reasons. 6 is a bit difficult to watch, so I recommend starting with the first episode instead.
