15 Park Avenue- sunshine doesn't always get through all windows

When I watch movies at home, I usually watch them in instalments, a little now, and a little later and later and later. Sometimes my films stretch to days, sometimes to weeks. Very few films captivate my attention. Like 15 Park Avenue did. I was so engrossed, sitting on my couch with pain in my heart, and tears in my eyes, I didn't realize that the movie had ended, of course the movie's climax was abrupt to add to my curiosity. My heart surely went out for Konkana kind patients (schizophrenic), who are entitled to a life sentence of pain and grief, for no fault of theirs.

For those of you who are not aware of what 15 Park Avenue is, here it is in a nutshell (review from apunkachoice.com)-
It is the address that exists only in the mind of a young schizophrenic girl. It is on this address her imaginary husband and children live.
Aparna Sen’s movie ‘15 Park Avenue’ is a touching film with a sensitive subject. It is a film that will appeal to selected audience, not the masses. The movie is slow paced and the culmination to the story is open-ended.

The film awakens in you, a transcendent part, that probably has been lying dormant for time immemorial. In this world where millions of beings suffer from millions of diseases, inborn or acquired, we live a life full of luxuries, yet there's no dearth to the complaints that we have for various reasons. I am no saint, nor do I deny that I have my own share of cribbings. Am just trying to pen my thoughts here, those which crossed my small mind last night. On this planet, where misery and agony reign, we are lost in our own world, worried about getting a job, tying the knot, reproducing etc. Has the thought ever striked us to adopt a baby, give a life to the less fortunate. We are worried about the life that hasn't entered this world, when we have the opportunity to give life to an under- privileged one.
I am not sure if I am one of those who would practice what they preach. I am trying to be one.

So if you are one of them who loves to see real- life films that touch your heart, do not miss this one- a treat to the heart.
The climax of the movie is still a little bizarre to me, so those of you who could make it out- kindly highlight.
