"Louie" has to be the best show currently on tv, in that we're getting to see an extremely talented artist do something very very few artists ever have the opportunity to do, which is transfer their artist vision to the screen 100% unempeeded.....the fact he's given free reign to write, direct, cast, act, etc and is able to express his voice directly to the audience is incredibly refreshing.
Not saying that art can't be expressed in other ways (The Wire pulled off various directors expressing different writers messages for instance)....but it's incredibly valuable to see a single artists vision all the way through as it was intended.
Television/Film is one of the few mediums where it's become standard for multiple artists (writers, producers, directors, actors) all attempting to input their own creativity into the final product.....whereas with books, paintings, standup, etc we're often hearing/seeing/reading a singular artists vision, making it a much more (to me) satisfying.
Makes something like "Louie" all that much more enjoyable in the rare occurances we get it.
