The problem is that there really isn't anything beneath the surface, no grander theme a la an Unforgiven. Most characters are well played archetypes, and aren't bothered with being given dimension. It won't challenge you as a watcher to decipher its meaning, and is very much 'what you see is what you get.' Fortunately, what you see is visually lush, with well composed shots and a very period-accurate feel.

The well shot Lawless is ruined by it's own lack of ambition and fluctuating impetus on it's heroes. it's well acted on the whole and I believe Guy Pearce gives a stand out performance (just as in Hannibal, his make up gives him leverage).
