I don't know why I decided to watch this gem at 3 in the morning. This is one of the best horror movies so far this decade, it doesn't rely on jumpscares or loud noises like most horror films its more of an unconventional masterpiece. I loved the tension created in this movie and the editing choices were phenomenal and actually unsettled me alot. The acting in this movie is superb especially by the females in particular Toni Collette who actually in my opinion gives the best female performance of the year. The film does not feel claustrophobic but it does feel contained in these particular locations which adds to the horror of this movie. This is Ari Aster's first feature lenght movie as a director and now he's on my radar I can't wait to see what he does next because he has crafted this movie to almost perfection. The ending has to be the best but also the most unnerving endings I've seen. The only flaw I can think of is the exposition which I get it that in such movies characters have to speak out the exposition but I felt this movie would've been better with less vocal exposition like The Shining. In the end, Hereditary is a very gripping, unnerving and unconventional horror film the best infact since The Babadook, it combines the elements of art house and horror very well and its a must watch for all horror fans but viewer discretion is advised because of it's disturbing nature. I give it an "A+" and "9.5/10".
