Last night I finally saw M. Night Shyamalan’s Knock At The Cabin. It’s more of a mystifying situational conceit than what most of us would call a movie or even a campfire tale. It's based on Paul Tremblay's "The Cabin At The End of The World," which I haven't read. But the screenplay, co-authored by Shyamalan, Steve Desmond and Michael Sherman, feels like a surreal dream (i.e., arresting impressions minus a compelling narrative) that was never developed into the kind of thing that most films need -- i.e., a story that coheres.
