I know people are probably sick of me linking to
a. The AV Club, and
b. Louis CK stories
but honestly, this second season of Louie was one of the best seasons of TV I've ever seen. (And 'Duckling' was one of the best episodes of any TV show I've ever seen). Reading this background on the production of the first couple of episodes is fascinating.
Also, much as I hate to say "X is the new Y", anyone else get the feeling that Louis CK is taking the reins left over from when Woody Allen packed up for Europe? No-one else is making New York seem so gorgeous.
