I watch a lot of horror movies and it's rare they leave a mark on me like a drama would, but this movie is different.

It sucks you in and makes you totally empathise with the characters before taking you on an insane roller coaster ride of violence and terror.

The horror 'scenes' aren't run of the mill jump scares, they are methodical and well placed. And this is not a run of the mill horror movie, this is a psychological twisted film.

The whole movie had me feeling uneasy throughout, so I knew it had done a good job.

It doesn't just give you surface scares but gets into your head and really makes you think.

And the ending... go watch this movie if you're a fan of horror. If you aren't a fan of horror I'd avoid as it is not for feint of heart, coming from a horror film buff! This is genuinely scary!
