How sad is this?

I saw this movie before reading any reviews, and I thought it was very funny. I was very surprised to see the overwhelmingly negative reviews this film received from critics.

A terrific literary drama and character piece that shows how the process of creating art can be seen differently by those doing it and those looking at it from the outside.

One of the film's great tricks is that, for a time, you think it will go down a rabbit hole of unrealistic glorification.
