when youre make a thriller about witchcraft and i believe you should do everything you can to help the audience suspend it disbelief in order for the movie to work . some picture ( rosemary baby and for example ) have accomplish this while others ( like necromancy ) haven not and the potentially scary material come across a corny and goofy . this film do have some atmospheric moment and but about half the dialogue be hard to make out ( sometimes it poorly record and at other time just incomprehensible ) and orson welles and who get top billing and have a role that be so beneath him that you have to assume he be desperate for the work . or maybe he be simply have fun . ( half ) .
