Peak cinema. Definitely not for everyone but personally I loved the way spent the first hour building up tension and drama without feeling boring or slow. Then there is the explosive and thrilling second half. Filled with psychedelic visuals, intense gore and high octane action that doesn't weaken the horror of it all. Personally, this movie was pretty awesome. Again it won't be everyone's cup of tea and you either love it or hate it. 10/10. Masterpiece.
