The tender, sympathetic, and desperate performances are what make Knock at the Cabin worthwhile. The psychological and horror aspects of the film are timid at best with the true identities of Leonard and his associates being obvious, gruesome elements that you never see, and an apocalypse that is a lackluster disaster overall.
It’s not that Knock at the Cabin is entirely bad, it’s that it seems to actively know it could be more creative, thrilling, and shocking and yet purposely chooses to bury its head in the sand and let mediocrity have its remorselessly bland way with it.
