The movie gets off to a promising start, featuring an initially unpleasant central character, well-executed practical gore, alongside some noticeably flawed computer animation. However, the pacing falters at times, and the main character eventually addresses the audience directly. There’s been considerable discussion about the film seeming to mock horror enthusiasts, though not everyone in our group is bothered by that kind of thing. The ending feels unpleasant, and the last image raises further uncertainties. I was enjoying most of it, but those final moments really undermined things. Viewer discretion advised for depictions of intense physical violence, sexual violence, graphic gore, pervasive profanity, suggestive content, mature themes, substance use involving drugs, alcohol, and tobacco.
