I don't usually review 7 year old movies but I'm a big fan of Zal Batmanglij and Brit Marling, a very underrated duo. I think they're very talented writers and Brit is such a great actress. Everything they've made together is imaginative and provocative, way more interesting than 95% of the slop Hollywood pumps out. This film is really good as most of their other work, like The Sound of My Voice and The OA.
Highly recommend.
