THE NUN (MA15+) Not habit forming, US, 96 min
The title character here bobbed up briefly as a vicious demonic presence in The Conjuring 2, looking like the dentally challenged, mentally deranged sister of ’90s rock star Marilyn Manson. Now we get her origin story, which hauls us all the way back to a convent in 1952 Romania, where she greets all who enter with bared fangs, bad breath and awful housekeeping standards. The banter between the most prominent visitors — a stoic priest, a naive trainee nun and a local lad named Frenchie — stilted and wilted in the extreme. As for scares, the filmmakers keep dimming the lights, shaking the camera, turning up the volume and hoping for the best. All that appears before your eyes is one of the worst movies of 2018.
