I write this review as a horror fan, seeking to inform other horror fans of what to expect with this film.
I'll be brief: like so many others here, I am drawn to extreme cinema, with visceral, shocking sequences of gore and violence. Honestly, I'm even down for cheesy, B-Movie style special effects. I love practical special effects, I love slashers, I love horror, and I love films that seek to push the limits. Naturally, Headless made its way onto my radar by seemingly checking all of these boxes. Like others, I had heard a lot of hype about this film, and was very excited to get my hands on it. (Minor spoilers ahead)
First the positive: The first 10ish minutes of this film are truly shocking and captivating moments of violent cinema. There are some unforgettable images in there, such as the killer sitting underneath the blood pouring from a body above him, the removal and eating of eyes, the infamous "head-hump", etc. The grain-y, 70s film visuals really work here, and the vibe is chilling and effective. A grim, fantastic start.
Now the bad: Not only does the film go absolutely nowhere here, but it's shown you most of its tricks and surprises right out of the gate. There's more eye-eating, more decapitation, more severed-head-copulation, but its nowhere near as effective as the first sequence. The directing gets really questionable here too, especially during kill scenes (disorienting is one thing...sloppy is another entirely). There's a backstory, but its pretty boring and predictable. There are other characters, but the cheesy acting and dialogue rarely comes off as funny/charming, and is almost always forgettable. It becomes clear almost immediately that this idea cannot sustain a full film. And yet here we are.
At the end of the day, this film's cardinal sin is simple: it's boring. Despite all of the gore and torture, this film will really struggle to capture your attention, and for a film like this, that's really not a good sign. It just goes to show that there needs to be SOMETHING more in order for a film to be truly shocking, sick and scary, and that "something" is not recycling the same 5 special effects tricks over and over.
The first 10 minutes are worth your time. After that, switch to something else. Truly wasted potential.
