It is an absolute masterpiece! The script, acting and music are all phenomenal. It is filled with intense emotions that will leave even a stone hearted person - teary eyed.
It touches a number of themes including the India-Pakistan relations, gender equality, life of a prisoner, cultural diversity, and weaves it all together with the central theme of true love.
The selflessness and unconditional nature of love, coupled with the presence of solace in a lover's mind even in the midst of unbearable pain, leaves the viewer stunned. The biggest and the most beautiful take away from the movie is - True love, even if it is unrequited, never hurts provided you love truly.
Just like the tale of eternal love that it presents, this movie shall remain evergreen.
