Man, I did not expect this movie to be so BRUTAL! A lot more art-house and slow when compared to movies of its ilk, but I have been clamoring for another film along the same lines as Martyrs or Frontier(s), and this film really delivers. I haven't seen a movie go for this style in so long, I was worried that directors had given up on the sub-genre for good. I'm happy to say that this movie would be at home with the likes of the more disturbing ones.
Everything works so well in this film, from the directorial style to the acting to the gorgeous cinematography, but I would be remiss if I didn't mention that this film is SLOW and extremely deliberate. While the few scenes of actual violence are beyond disturbing (with one scene so shocking I didn't even know how it got past the ratings board), but the rest of the film was a dreary, depressing familial drama(?), although that wouldn't be the appropriate label for a film about a pair of siblings who are taking after their father, a vicious serial killer. There was just so many scenes of this brooding woman, allowing life to beat her down, and when her brother finally got to work, it happens quickly, and then we are back to scenes of her moping around, looking crestfallen and despondent. I understand why this was done in the context of this style of film, but it's a real drag when you get that rush of brutality to only come back down to so many scenes of mediocrity.
If you're a fan of movies like Martyrs, Inside, High Tension, ect. This movie will be right up your alley. It's extremely and deliberately slow, but stick with it. The pay off may be worth it, depending on how patient you are.
