Somebody asked recently on the TCMMF group how people felt about spoilers in subject headings. I am unsure.

For example, the summary of this movie (in the 520) hints that something sketchy is going on:

Behind closed doors, patriarch Frank rules his family with a rigorous fervor, determined to keep his ancestral customs intact at any cost.

But the subject headings are much more direct:

    650 _0 ǂa Serial murderers ǂv Drama.
    650 _0 ǂa Cannibalism ǂv Drama.
    650 _0 ǂa Family secrets ǂv Drama.

What do you think? Do these headings aid researchers? Or spoil the story for film fans? Does it depend on the type of library?
