I'd forgive you if you were crazy, but you're not. You're weak. 
Revenge movie is not a man go and shoot all his enemies down. I saw in this movie the lead character Dwight was eager to avenge his parents' death, but fear in the eyes, trembling hands and amateur killing instinct, totally a realistic appeal. Indeed an excellent performance by the lead man. A simple story, but awesomely developed with every scene. Almost a masterpiece work of this director that quite reflects the Coen brothers style of filmmaking.
The word 'revenge' needs an explanation why it's taking place and here it won't bother to describe in a flashback, but makes sure that you get the reason behind it. It is kind of tricky to understand, it might be either make-up or graphics, but all those wounds, gunshots and bloodsheds were looked surreal. Kind of running and chasing type of tension movie, whenever those crucial clash happens, it pulls us to our seat's edge. It serves potentially what viewers would expect from this genre. A must see for those who like gore and vengeance themes.
