I was quite hopeful after watching the first 10-15 mins but it turned out another run of the mill movie with no substance.
Similar to what happened with Gangs of W. The starting was intense, when they explain the coal syndication and how it evolved to pseudo-criminality and progressed to organized crime, subjugating with India's map in the background. That was awesome....! Then it went South (with multiple story lines), and hit the crapper. Total let-down.
Am sure, Gunday does something like this too...! I feel this movie will be a hash-pot of: Kaala Pathar + Sholay. Friendship with the backdrop of coal.
"one cannot come clean when dealing with coal..!". LOL.
