10 Horror Movies You Shouldn't Watch With Your Parents

10. Excision

The thought of watching high school sex comedies like American Pie or Superbad sitting next to your beloved parents is enough to make you feel incredibly awkward. Just imagine, then, what it would be like to watch Excision with them, which takes the premise of a teenager seeking to sleep with someone for the first time and twists it into something much more menacing.

Winning a handful of awards on the festival circuit, this cult gem from Richard Bates Jr follows outcast Pauline (AnnaLynne McCord) on her aforementioned lustful quest. However, it soon materialises that Pauline's tastes revolve around blood and mutilation, something she fantasies about frequently in vivid detail, ensuring you'll never make eye-contact with your mum again.

In addition to Pauline's devious exploits, the high schooler aspires to be a surgeon, a dream she begins to pursue in a bid to impress her overly-controlling mother. We won't spoil how this manifests itself in the film to avoid spoilers, but it does make for a powerful and shocking climax.

Also featuring Malcolm McDowell and cult king John Waters himself in supporting roles, this grizzly flick is exactly what will get you off the Christmas card list this year.
