I wasn't sure exactly what to expect of this film. The trailers were excellent, but that isn't always indicative of the quality of a film, so I was unsure.
However, I must say that this film is truly wonderful. The characters, the sets, the twisted plot -- I have almost no complaints about any aspect. The only thing I'm not wild about looking back on this movie is that the fake blood isn't the best quality fake blood, which is kind of a shame because it tended to look like red paint at times. That aside, this film was a crazy, intense viewing experience that left me already anxious for my second viewing.
(Also, if you're a fan of Alexander Skarsgård like I am, you'll definitely love seeing him dive deep into his darker and more twisted side -- He performs exceptionally, as always.)
