Marc Maron is a pessimistic individual. I can relate. Sure, I'm sure he plays it up on the show, but the character is still very relatable and overall just an interesting person to see go about his day. To think that he is both the creator, a producer, a director and a writer on the show is astounding. He is a lot of the creative force that makes this show as great as it is and it shows. His character on screen has such an idea of what he's involved in. I'm sure playing himself helps but he's really a fantastic actor, fitting into every moment perfectly. Much like Louis CK, it's amazing to see someone excel so much in their own show yet have much experience beforehand. Both were comedians with bit roles in various things, never really showing their true talent till their respective shows. Hopefully Maron follows suit with CK and appears in more movies (ie. CK in American Hustle).
This brings me to the unique part of the show that really solidifies that this show is from 2013-14, it's embrace of the present. No, Marc Maron isn't pulling a Frasier Crane, being a radio host. No, instead he hosts a podcast, the 21st Century answer to radio. It adds a dynamic to the show, much like radio, where different guests are able to come in from different parts of the industry and it logically makes sense in the scheme of the story. Makes guests feel less shoehorned and more natural to the flow of the story being told. Plus, Podcasts are the in thing right now. If you're in comedy and don't have one then something is either wrong with you or you're too big for them.
The entire first season of this show is on Netflix and the second season just premiered last Thursday. Do yourself a favor and get caught up. Pair this with Louis and you've got yourself a damn fine summer of TV viewing that feel very similar in tone.
