10 Horror Movies That Will Make You Glad You're Single

The subject of toxic relationships gets brought up a lot in cinema, as a dysfunctional couple can make for some great stories and unsettling truths.

Still, when it comes to picking a pair who might be the most toxic, then Anna (Isabelle Adjani) and Mark (Sam Neill) from Possession are an obvious shoo-in. These two make Midsommar's Dani and Christian look like the Addams family.

Possession is a disturbing, psychological horror movie that follows a married couple as their relationship dissolves. After returning from performing spy work in West Berlin, Mark is informed by his wife that she wants a divorce. Their behaviour soon grows erratic as Anna breaks down, and Mark becomes increasingly suspicious.

The performances from Adjani and Neill carry this movie, as they're both uncanny and horrifying. Adjani, in particular, thrives when exploring the unravelling mind of a woman losing her sanity. Her haunting performance that will stick with you long after the credits role.

It's a horror movie that explores complex themes and acts as a compelling character study of two people trapped in a relationship they don't know how to fix. It kind of puts you off the whole "marriage" thing.
