“Skinamarink” is a Shudder-exclusive film that had a brief theatrical release earlier this year. Some horror fans say that it tapped into primal childhood fears and have proclaimed it the scariest film of the year. Others (including myself) have proclaimed it 100 minutes of barely watchable static shots of interior walls and kids’ feet. It’s more about mood than incident, so it may pose a Manos-level challenge. I think you could have a lot of fun with it, however!
