There are some plot points in this movie that are kind of questionable and require suspension of disbelief, but overall this was great to watch.

The story was harrowing and I felt mind-blown by the way things were playing out, even when I realized things one second before it was revealed. The tone of the story was really doom-and-gloom and I felt like it perfectly encapsulated the vengeance theme, from the very first second to the very last scene. Great movie— one that's not afraid to embrace its darkness.
