I like to sometimes call them “IMDb-ites” because they look like the kinds of things you would see on IMDb with no picture attached and barely any info surrounding them.

Rules:
1) Anything PG and below is perfectly fine, PG-13 should be treaded carefully, R and X aren't allowed at all.
2) Conceal spoilers via invisible text (recommended) or square brackets (not recommended, as the only way to see them also risk damaging formatting)
3) Don't link to the IMDb entry, just say the name. This is because IMDb's webpage links to unallowed SocMed platforms, and this topic (due to it technically being about an entire genre of film or TV show) is already massively at risk of being closed.
