This is kind of a difficult show. You have to pay attention. It's a slow, theatrical television experiment that is both incredibly modern and very old fashioned. It's investment TV, but the ROI is big. The entire series will get you thinking about the infuriating messiness of family and relationships, and the future of TV.
I have watched a lot of Louis CK's stand up comedy and it seemed to me that his amazing humour came from him extracting the absurdity of life and talking about it on stage in a way that was both very funny, honest, and engaging. Even though the episodes of Horace and Pete feel formatted more in the way of a play, to me it is still fantastic in the same way. Family and life can be infuriating because as we grow up, we see that the more we know about family/life/universe, the more we realize that we know nothing (that whole Socrates thing), but that doesn't mean we give up hope ... instead we can find it absurdly funny and laugh in the face of absurdity, and try and learn from it to move forward in a better way. Especially when there is a master funny man like Louis CK to extract amazing thought lines from the absurdity. In this way it is an honest reaction to the confusing nature of life instead of simply trying to create a sanitized narrative to our lives that might make us feel less fear, but doesn't really address the reality. Anyways, this is a really good show, I find the dialogue really great, the acting great, and the jokes great, and therefore I find it ... very great! Thanks Louis CK!
