Karl von Randow’s review published on Letterboxd :
Set almost exclusively inside the protagonist's cabin, the film has an enticing claustrophobic feeling combined with a murder-mystery sense of searching for the truth - without the violence or suspense.
It's an unassuming, simple film. It mostly stays within sensible, rational bounds as the protagonist tells his friends that he's a 14,000 year old cave man. A nice film to watch on a wet evening.
