It's a relaxing and positive movie. Humans are meant to interact with one another. Often, the decision is - she is out of my league, or he is from a different cast... countless reasons come up in mind, to not be in proximity, with the person of interest. Years later, we find ourselves trapped in relationships we have nothing in common with.
In Photograph, the guy does nothing and something - at the same time. He is timid, yet a man, must express his desire - yet knows, their worlds do not have anything in common, other than perhaps the air they breathe.
He takes her to cinemas, infested with rats; he did not borrow money or create an illusion. Above all he was transparent and truthful. Left it to her, to decide what she wanted.
Just because you woke up pretty, there is no assurance, you will have lunch like a diva. Similarly, the man met her in reduced circumstances, by the end of the movie, he does what he can to give her modern amenities, he knows she is accustomed to. This is real love.
Men and Woman - both are equally blind, these days. Great scriptwriter/director. Well-acted, a gem of a movie may it get more publicity.
