Jeremy P. Beasley’s review published on Letterboxd:
Alverson might be my favorite contemporary director. He’s totallly uninterested in giving you the whole story. You’ve gotta do some work. The Mountain is his most calculated work yet. Every frame is ridiculously intentional. Goldblum delivers a fantastic and haunting performance as a celebrity lobotomist at the end of its widespread use. He’s grappling with the fact that his profession is suddenly obsolete. Despite the horrific topic, the tone is dull and poetic, a far cry from say, Shutter Island. The posters show Goldlum, but the real star is Denis Levant. I can’t even explain how good this ends.
