The story seemed something akin to 47 ronin. A lord is disgraced and his retainers seek revenge by storming a fortress is the general outline of the story. That would have been cool but there is a fair amount of time spent on the commander of the forces proving he is a broken man who has fallen into drinking and whoring. That could have been a bit shorter, but it at least felt convincing.
The actually attack on Gezza Motts , read bad guy, fortress could have been longer or filmed with a bit more impact.

I am not sure but some of the sets seemed to be the same as A Game of Thrones and there was a water skin that looked the same as Sandor Cleganes. That was a
All in all sort of a meh. I have seen worse movies, Solomon Kane comes to mind. This is not as good as Children of Men though.
