Gore Films

Troma and I had a discussion recently on what qualifies a movie to be a gore film. I realize that the overall definition is a splatter film or gore film that deliberately focuses on graphic portrayals of gore and graphic violence.

But can movies that show only a few scenes of gore be considered a gore film? Or are they just gory? Is there even a difference? Does the gore have to be the main element of the movie for you to consider it a gore film?
