Interesting. Didn't quite go as it started. Starts out boring. Not sure if there is a story in this intelligent yet essentially lazy heroine. An earlier version of the absurdly overrated film Brooklyn. A heroin with no story to star in. 

And then it happens. Her decent into insanity is so sudden and so casual that you get a mental whiplash. I might never look at mental health issues quite the same way. It is not such an alien issue to me anymore. It maybe everywhere. Just a matter of varying stages.  

And what really is insanity anyway - to some degree - even as an exaggeration - it is perhaps nonconformity - specially when practiced  by a social class that hasn't yet made it to the mainstream - or is still stifling under its own imaginary or real bell jar. 

Despite myself, I liked Plath's Bell Jar.
