Bojack starts filming a new movie whilst trying to display a new attitude, but emotional problems get in the way.
This is a strong start to the second season that starts and finishes in pretty dark places for Bojack.
In the middle of these two bleak moments we see Bojack attempting (in the most desperate and superficial way possible) to show he is different person and (in an over the top way) it feels quite familiar to me. It is in some ways funny, but generally it is pitiful.
Much of the humorous banter between characters is very well written, but there is only so much you can laugh when there is so much pain underlying a character portrayal. I enjoyed the black humour about the 'dangerous' cable on the movie set, the reference to Sebastian St. Clair, and most of the banter involving the character Kelsey Jennings.
