A simple premise that is presented in a straight forward simple way that works perfectly albeit in a nonchronological fashion. There are too many revenge movies generally and there are definitely too many revenge movies that suck. And the top reasons that they suck is usually that they are just super wimpy (see Taken, Taken 2, Taken 3, Taken 4 etc) or that they are poorly made (acted, directed, shot etc). At least in my experience anyways. This movie is none of these things. It is super well made (acted, directed, shot, written, etc) especially for this genre. And it may be a number of things but I would not say that it is wimpy in any way. Unflinching, violent, gory definitely but also sincerely and legitimately presented. Fair warning that it may take a bit to adjust to the gutter English spoken by the characters if you're American like me but well worth it if you're inclined to enjoy bloody bloodbath revenge movies like this one.
