I did not dislike this movie. It was more or less exactly what I expected. As a fan of the creepy aesthetic of David Lynch and movies that challenge the audience I wasn't too disappointed. I love the concept and appreciate the approach but ultimately if you are going to ask an audience for 90-120 minutes of their time I think a film should give them more than Skinamarink delivers. Still, from a first time filmmaker it's an admirable effort.
I far prefer slow burning horror films that play to the fear of the unknown and an have an underlying sense of dread (The Witch, Hereditary, and The Blair Witch Project are personal faves). Skinamarink tries to play in this arena but doesn't effectively use any cinematic tools to build tension or make the viewer anxious. No soundtrack, very little camera movement, and not enough dynamic use of light and shadow. All things that I think probably could have been achieved, even with a miniscule budget. Thematically it starts in a very minable vein but then doesn't actually develop what amounts to a fairly universal experience of fear (i.e. Being a defenseless child abandoned by caregivers). We feel isolated and alone with the children but are distanced from the sense that anything frightening is happening I think because so little of the film takes place from the children's perspective. It did get me thinking about how to make a horror movie driven by fear of the unknown. If you want to make something universally scary how much do you need to show the audience to prime them to be afraid and how much can you leave to their imaginations? In the end Skinamarink asks the individual viewer to fill in too many blanks for it to be an effective horror movie in my opinion. Truly neurotic people will probably find it unnerving and anxiety inducing but aside from a couple of cheap jump scares nothing particularly interesting happens. My impression was that the vast majority of people will most likely find the movie a waste of time and for that reason I cannot recommend it. But if you like a challenge, are home alone on a stormy night, and/or are capable of letting your imagination run wild then, sure, give it a shot.
