This was more of a emotional than a factual movie.
If you already know about Kashmir Exodus and have researched about it (i would only recommend Wikipedia as a trusted source cause it shows stories of both sides) than yeah, you may or may not watch it, doesnt matter. Its not a must watch, but its entertaining.
If you dont have much knowledge about this issue, i would recommend this movie to be a good start to know more about the exodus.
This movie doesnt exactly explains the factual information (Pakistan's involvement, failure of government, weather problems etc)on why this dilemma arose which i think is necessary to avoid any kind of hatred towards other community.
To anyone, i would suggest after watching the movie do research about it. And while doing so keep a neutral mind.
And to all my Hindu friends, "Not all Muslims were bad. Only in some regions the locals supported the terrorist. In other regions, their voice were shut by the militants, or were killed".
