I think this screenplay was absolutely amazing, based on the true events is Susanna Kaysen's life, it dealt with her being institutionalised, which is a very difficult issue to talk about, more so to create a movie.
It was such a sad and endearing story and the book, screenplay and the movie were all terribly sad.
On a different note, I found the movie a little more appealing which is a rare preference of mine as usually I prefer to read, being the avid reader that I am.
Overall a very good but tragic screenplay that will have you in tears.
