Valuing relationships and giving time to that is what this movie teaches us. Science fiction is used to deliver this message but it can be well connected. One of the most underrated movies of Bollywood.
It really gives an important life lesson.
You will definitely feel connected to your dear ones while watching the movie . It will make you cry at some point . May be at some point you will feel bored but at the end you will feel that you gained atleat something by watching the movie.
And that's a great feeling....
