I saw this movie when it came out 30 odd years ago, I was only a child and remember being blown away by it. It was all the rage and even now when I watch it it remains fresh. One of those movies you can watch repeatedly and never get bored.
The Late great Sultan Rahi was at his absolute peak when this movie was released, Mustafa Qureshi's Noori Nath was arguably an even better character much like Gabbar Singh blew everybody else away in Sholay.
Without question the best movie to ever come out of Pakistan. Great songs coupled with astounding dialogue that elevates this movie to a pedestal few, if any can touch, just as Sholay does in India. Most fans can quote the entire movie from memory.
If there is only one Pakistani movie you will ever watch in your life, make it this one.
