This is absolutely essential viewing. The film creates an intensely uncomfortable feeling, delivering shocking moments and considerable violence. It’s a descent into the psyche of someone deeply troubled; a mind that – just like your own might be – struggles to process what it uncovers. The movie's narrative is exceptionally clever, incorporating dark humor, a pervasive sense of confusion, and numerous unexpected developments that keep you engaged. While there are many revenge thrillers out there, this one stands apart as the absolute best.
