10 Best Animated Horror Movies

Come on, what else could have earned itself the top spot on this rundown? After all, it's not like Perfect Blue or Fear(s) of the Dark were the basis for your formative nightmares.

Apologies if they were, those really shouldn't have been early viewing.

Released direct-to-video in 1998 and becoming a surprise success for Warner Home Video, Scooby Doo On Zombie Island was an iconic entry into the long-running Hanna Barbera franchise about a set of meddling kids and their sort-of-talking dog.

Coming hot on the heels of the lighter, more zany (and still underrated) Pup Named Scooby Doo incarnation of the series, this shockingly dark Scooby Doo instalment remains beloved by the many millennials it scarred thanks to its one effective twist on the show's reliable formula.

This time, viewers were promised, the monsters are real. And indeed they were, and really terrifying for that matter, as the loveable gang went up against not only legions of the undead but also ageless cat people who controlled them in a still-effective slice of horror comedy which introduced a generation of kids to the joys of being scared s***less.
