After seeing "Fanaa",when we were getting out of the theatre,someone commented...why did they need to show "Aamir" dying in the end?
Imagine the story with a different end,and see if it remains as poignant and as effective....
Well it cant.We must swallow a few bitter pills if we want to learn a few important lessons in life.
The decision which "Jooni" takes was ,as she says,was one of the two bad decisions she had to take.....She took the one which was the need of the hour.
We do take such decisions in real life too.And learn to live with it.
