I don't have a ton to say about Mulaney this week, but what I do have can be pretty readily boiled down into three points:
1) This episode was overall significantly better than the pilot, with Mulaney seeming much more comfortable on camera and the average joke quality going up.
2) Mulaney still isn't nearly as funny as it should be, and it's far too willing to sell out its own characters and universe for a cheap laugh (my sitcom pet peeve).
3) Mulaney is at its best when it's coming from a mean, cynical, and incisive place. If it ever decides to live there instead of just visiting a few times an episode, it will be an excellent show.
