“The Long Night” (*1/2 out of four) was a grueling horror melodrama about a young couple (Scout Taylor Compton and Nolan Gerard Funk) off on a weekend getaway which takes a nightmarish turn when a maniacal cult and their satanical leader (Deborah Kara Unger) descend on their cabin. Result is such a brazen knockoff of “The Strangers” that it’s strange they didn’t just call this a remake or a sequel but either way it’s monotonous and dumb. Compton and Funk previously starred together in “Triple Dog” but this reunion for them is a real dog.
