Nine scored verdicts, averaged, come to 6. The range runs from 4 to 8 — most of the usable middle of a ten-point scale. Metacritic sat at 59 from 37 critics on 23 October, and Rotten Tomatoes drifted around the mid-seventies all week as reviews piled in, so the aggregate number you see depends on the hour you look at it.
The spread deserves more attention than the mean. Reviewers agree about more of this film than four points of disagreement would suggest: the prosthetic work is good, the digital work layered on top of it is weaker, and Tom Rhys Harries holds the middle. What they disagree about is how much that costs a horror film whose whole pitch is a man turning into mud.
Practical whenever the face holds still
Watkins set the rule before release and described it in production terms. Matt Hagen’s face is a practical appliance whenever it is not moving. He named The Fly, An American Werewolf in London and Tetsuo as the reference shelf, and said Harries went through many iterations of the makeup across long sessions in the chair. James Gunn was reported, well before release, as having pushed for practical effects across the production. I could not find a named prosthetic designer or VFX supervisor on the film in any source, which is its own small indictment of how these credits get covered.
That rule is sound economics before it is sound taste. A prosthetic sitting still is the cheapest realistic thing you can put in front of a lens. It is a real object in the real key light, picking up the set’s bounce for free, with the grain of the film stock landing on it at the same time as everything else. No shader approximating sub-surface scatter. No roto. No match-move. Nothing to match, because it was never separate.
DC has run this experiment before from the other direction. Lanterns built a real ring suit on set instead of the CG one every prior adaptation used, and the reviews kept circling back to that decision the same way these ones circle Harries’ makeup. A physical thing in a frame buys you credibility you cannot purchase later.
Then it has to move
Here is where the money goes, and where this film appears to have run out of it.
Clay has mass. A face that melts needs viscosity, surface tension, and the particular way a thick material pulls away from itself before it lets go. It needs self-collision, so the sheet of it running down a jaw does not pass through the sheet beneath. It needs contact — with a collar, a floor, another actor’s hand — because a creature made of material that never touches anything reads as a decal. Every one of those is a simulation with a slow iteration loop, and a note from the director on Tuesday is a new cache on Friday.
Then that simulation has to be dropped into a plate that already contains a real appliance, lit by real lights, in the same shot. The lighting is baked into the prosthetic and cannot be adjusted, which means the digital half has to come to the practical half rather than meeting it halfway. And the hardest frames in the film are the handoffs: the dozen where a lit rubber face becomes a simulated one. Get those wrong and you teach the audience exactly where the seam is, and they will find it every time afterwards.
Which is more or less what the reviews describe. The makeup is called faultless in one notice and the computer work inconsistent in the next paragraph of the same piece. That pattern is what the production rule predicts. Still face, practical, excellent. Moving face, digital, variable.
Faces are also the one surface where audiences have the most training, which is why they keep coming up. Danny Boyle’s Ink went the whole other way and put an AI-generated Thatcher over a paid impersonator’s performance for thirty seconds. Both films are solving the same problem — a face that has to be something the performer’s face is not — and both land on the same answer: keep a human underneath, and spend the money on the transition.
The number
6, from nine verdicts between 4 and 8.
The high end came from British broadsheet and listings critics treating it as a body-horror picture, the low end from genre and comics sites comparing it to the rest of the DC slate. The gap is a disagreement about what film this was trying to be, which usually means the film was not quite sure either.
Budget reports disagree: somewhere between $30m and $45m depending on which outlet you believe, with $30m the figure that recurs. It opened in North American theatres on 23 October after $3.5m in Thursday previews, with weekend forecasts of $20m to $25m — a profile that, at this budget, does not need a Metascore in the eighties to work out.
