SilentDawn’s review published on Letterboxd:
A gratuitous, nonsensical nightmare beamed from a faraway planet. It's as if a group of martians tried to convert it into a format that mere humans could understand, but then they stopped halfway through and said "fuck it" as they sent it to their human representative in the form of Alejandro Jodorowsky. The Holy Mountain begins with a surreal ceremony and ends with nothing; the evocation of a scrambling mind eventually giving up. Rainbows make up the entirety of caverns, shit becomes gold, and a baby rhino chills in a fountain. Bonkers, out-of-so-many-worlds cinema.
