I can't immediately compare it to anything else, but I will say that Schwartzman is very good in the role and if it's not simply the sight of him that puts you off, you shouldn't have a problem with him in this. Very subdued and not particularly annoying like he character in Rushmore (which I did like).

The premise is that he's a writer for Ted Danson's magazine, working on his second book which is coming close to being due, but not yet close to being started. His girlfriend breaks up with him and he decides to start offering his services as a private investigator on Craigslist, with no experience or realized talent. Galifianakis is his best friend, though Danson as his boss is also very much his close friend. All three are pot smokers and that plays a bit in a few episodes.

The performances are all really good and there are guest appearances by quite a few other actors you'll immediately recognize (and may like).
