Amazing and timely show. This is not a comedy, it's _about_ comedy; which is written by depressed damaged people.
The core relationship between two broken and talented individuals set against the backdrop ridiculousness of the entertainment **industry**. Balancing extremes are the theme of the show as personal demons can be what sells the best, so self-awareness is how you profit off your pain, but also prevents you from doing what is truly best for you.
It's also about women from a woman's perspective, which is still pretty new, so the cinematic language may be unfamiliar to some. Very multifaceted, as women can compete and support each other simultaneously. No one can hurt you as much as someone who loves you.
Watch if you appreciate great writing and able to devote your full focus to keep up with the dialog. Bonus tip, stay for the credits, the song is usually an excellent emotional reflection of the episode.
