Elaine Fuentes’s review published on Letterboxd:
A film about the history of Mayhem that shits on literally every piece of their legacy, and Black Metal as a whole. Constantly saying that this is portraying "Real Norwegian Black Metal", and isn't for "posers", but everything, absolutely EVERYTHING, in this trash pile of a movie shows that it knows absolutely nothing about Black Metal. Absolutely disgusting; made me raise my score for Bohemian Rhapsody, something I thought I would never do, but this proved you can go lower than that. Contender for my least favorite movie. Poser.
