Violent: (
Objectionable Content)
Titles that include as an important part of their content excessive displays of cruelty, blood and gore. Any of the classical 'slasher' films would qualify for this keyword. The series
Black Lagoon would be a good example; as many of its chapters involve killer lolis, chainsaw mercenaries and flying body parts.
Creepy: (
Style) Self-explanatory -- if the title gives you the creeps, it is creepy. :-)
Occult: (
Story/Location) Titles involving the action or influence of supernatural agencies or some secret knowledge of them.
