“Missing Couple” (** out of four) was a perfunctory horror melodrama about a couple (Austin and Janna Jenkins) who set out on an adventure to renovate an abandoned farmhouse in rural Mississippi but fell prey to strange occurrences and ancient horror rituals that resulted in them missing. Strictly for those who can’t get enough of the found-footage horror genre as film liberally rips off “The Blair Witch Project” at times but does have a few jumps and spooks to keep it watchable at times. On the whole, though, film is “missing” the vitality and shock that “Blair Witch” and others had over 25 years ago.
