Avengement may seem like your cliche straight forward revenge story that we've seen countless times. But It's so much more than that, here we get to see how a character change and try to survive the constant onslaught of prison inmates trying to kill him. How he overcomes those situations and how you are rooting for him to succeed, But with in the underlying caricature comes a story of betrayal, deceit and pain. The movie comes with suburb acting from Adkins, which i think it's his best, and of course the fight scenes are equally grotesque as well as amazing.
Overall: I recommend this movie 100% whether your an Adkins fan or an action movie aficionado.
P.S This film will go under the radar but in the future it will be a classic.
