I too am a giant Maron fan and loved the doc just on a storytelling level - the arc of losing Lynn to taping the special about it with everything in between. Maron's so endlessly quotable I took this down: "I'm just waiting for something to destroy me...and I think it's me." Me and my friend are still planning to get Maron tattoos of a pair of glasses and his quote "I'm not for everybody, I'm barely for me" The best .
Last night I watched Come See Me in the Good Light and it has a similar arc for the story except it's a poet and her cancer battle to get back on stage. Highly recommend if you liked the arc of the Maron doc.
