780 The First Power (1990)

 A  superfluous  sprinkling of  occult  trappings borrowed from The Omen franchise doesn't disguise that  the premise is lifted wholesale from House III: The Horror Show  and Shocker.  There's  also  a  zombie  element in the  shape of Lou Diamond Phillips as  Rex, the  cop plagued by repeat visits from the serial killer he sent  to  the  gas  chamber.. Having a plank as leading man robs the film of  any  chance  of  rising  above  its  seen-it-all-before  dullness.
