LOS ANGELES, April 27 (UPI) -- Hokum , in theaters Friday, is an effective horror movie with a challenging protagonist. Lovable Adam Scott embraces his dark side and the film meets him there. Author Ohm Bauman (Scott) visits the Irish hotel where his parents honeymooned to scatter their ashes. He does not make fast friends with the staff. Bartender Fiona (Florence Ordesh) tells him the honeymoon suite has been locked for years since owner Cob (Brendan Conroy) believes he trapped a witch there.
