For a franchise that has subtle title like "I Spit on Your Grave", it certainly has no shortage of gruesome scenes. I'd even say it's a level above what most slasher flicks can pull off. Unfortunately, aggression alone doesn't cut it, the movie has a very touchy subject and it lacks any refinement to deliver anything consistent aside from random rage trip.
In what seems to be a mix between vigilante and horror flick, the protagonist literally whacks people she deems evil. As one might expect this is far from rainbow and sunshine, it's pretty much one of the bleakest and profanity infested B-movie in this year. The unapologetic style might work for a bit, but it alienates the audience and certainly isn't a way to draw sympathy.
It first tries to introduce the protagonist after abusive past, then it falls apart when she dives into insanity. Using a heavy theme isn't easy. Some other vigilante movies with female leads like Jodie Foster's Brave or even Jennifer Lopez's Lila and Eva, while not entirely perfect, but they do have some empathetic appeal. This movie has none of that and it doesn't really care.
What it does have, in spade, is brutal carnage. It has some of the most surprising and striking gore scenes, and they alone might just warrant some viewing as legit slasher flick. However, the overly combative nature won't win any audience. At some points the intrusive thoughts are chaotic for the sake of being chaotic alone.
This one is for gore purist only, it's a really aggressive rendition of vengeance premise and while it most likely attract the horror fans, it may not be appealing to casual viewer, especially if they're not familiar with the franchise.
