15 Best Horror Movies Of 2017

13. Split

Going into Split, audiences didn't have any idea what to expect. M. Night Shyamalan doesn't have the greatest track record - especially when it comes to horror - and thus intrigue spread like wildfire when his latest film enjoyed an uncharacteristically warm response from critics.

Headlined by the always-great James McAvoy as a man suffering from a split personality - 23 split personalities, to be exact - the psychological thriller slowly transformed into a strange supernatural slasher the more it progressed.

Blending surreal comedic beats with the otherwise straight horror, these moments of levity helped cement a purposefully unpredictable tone, and the sharp changes in personality as McAvoy bounced from innocent child one minute to a pervy sociopath the next made the flashes of true horror even more pronounced.

It's not perfect, and an uneasy sub-plot focused on surviving abuse doesn't communicate the best message, but thanks to a great central performance, some brilliantly tense moments and a mind-blowing final twist, Split ended up being one of the biggest surprises of the year.
