“The Amityville Harvest” (*1/2 out of four) was a vacuous horror story about a documentary filmmaker (Sadie Katz) and her team staying at the famous Amityville house while researching its liquor-smuggling and ghost history and soon begins to suspect that its mysterious owner (Kyle Lowder) may not be who- or what- he says and she tries to escape with her life. Umpteenth movie in the endless “Amityville” cannon is just selling a name, as dull characters go through the motions of a routine haunted house story. Writer/director Thomas Churchill pops up in a meaningless cameo on an archive video.
