“Sour” (* out of four) was a moribund bore about a seedy detective (Adam Berardi) who moves with his niece (Natalie Maher) to a house that’s (what else?) haunted; as if that wasn’t enough, the landlord (Bourke Floyd) turns out to be abusive and sadistic and tries to turn the screws on both of them and they fail to get out until it’s too late. Lifeless exercise in tired horror cliches fails to pulsate with any suspense or energy. Viewers who make it to the end of this claptrap are the real ones who will feel “sour.”
