Bill Arceneaux’s review published on Letterboxd :
Probably Christopher Nolan's best work to date. The level of stress and anxiety I had, caused by the mountainous tension and dangerous predicaments, took my breath away. The semi non linear fracture of time is - like with INCEPTION - threaded with the collective suspense. A horror movie that starts with the killer chasing its prey, centered solely on survival and rescue. Big and epic without wearing out its welcome. Probably the best movie of the year (thus far).
See it on bright film, if you can.
