Launched in the USA in 2015, Shudder is a streaming service dedicated to horror films that arrived in the UK in October 2016.
It offers hundreds of films and series to horror-heads for £4.99-a-month and also has it’s own rating system - marking movies out of five skulls according to users’ reviews.
Shudder subscribers are notoriously hard to please, with many classics like ‘Society’ and ‘Pieces’ only attracting four skulls.
We’ve had a tour of the archive to see which films have managed to score a perfect ranking on the UK site.
Here are 10 of them for Halloween - all of which have also scored a rating of at least four skulls on the (even more critical) US site.
9. Possessor
With 2020's 'Possessor', filmmaker Brandon Cronenberg proved he could more than hold his own against his father - legendary director David Cronenberg - when it comes to body horror. It stars acting heavyweight Andrea Riseborough as an assassin who performs her kills by possessing the bodies of other individuals. | Contributed
10. One Cut of the Dead
Tricksy Japanses zombie film 'One Cut of the Dead' was largely overlooked on its original 2017 release, but has since become a cult favourite that has attracted near-universal critical praise. It follows a film crew tasked with shooting a live horror - showing the film-within-the-film first, before things get clever...and very funny. Those who walked out of the cinema during the first third of the film must be feeling pretty stupid now. | Contributed
