Yes it does! But bear in mind that she published the book because she needed the money. She was a poet at heart. Her last poems are just terrible, and with that sense of foreboding about her death everywhere.

I liked The Bell Jar a lot, and it was sad to think she'd been through something similar at least at the beginning.

Also, about the film, I forgot to say that her two children were completely against it and refused to help with the making of it. They thing it's just a tabloid sort of film which shows their mother's darkest (and not always real) side. But go and see it if you can.
