Looks like a nutty film. Fans love it apparently. I mean I really dig into reviews when I am not totally sure of a film and this one looks promising for people genuinely interested in this kind of nuts.
Can't say it intrigues me enough to watch it but my taste in film has changed greatly and I know this is something that would be on my watchlist...years ago.
'Nutty'....hmmm? Says so little, yet so much. At least you didn't say 'Edgy'. lol I get that sometimes one needs to move away from previous indulgences in dark things and morbid fascinations of youthful idiocy, fo sho
There is a judgement of media that is tad artsy pretensious for the 'edge/outlaw/weird' aspects of film; often it is a VERY valid perspective, when judged from a certain, valid aspect but I'd have to disagree, here. As in terms of artistic integriety and visual engagement - it's a pretty beautifully made piece; albeit dark and sinister(but ya know, its a metaphor for real life and darkly pointless social institutions - being that we are all not pissing out rainbows

)
Also, more importantly, it is a narrative based on drug-induced experience - that is 'nutty', but in terms of expressing human spectrum experience; often of the ominous kind - I think we need room to project that, for catharsis and learning sake, within this present paradigm of stilted and pc politically controlled, era of claustrophobia. It expresses somethin needed.
Anyhoo, logically, this film in it's essence was inspired by the book,
Suspiria de Profundis by Thomas De Quincey - notably an opium addict, so understandable that it is totally, uncomfortable to some( as RL is enough). However, it's art expresses the irrational, the cultural and the subjective that has been forgotten or, supressed by normative standards; for this reason I think it has wonderful merit in expressing the darker side of life, in a catharsis, for those of us who, unfortunately, viscerally experience these socially cruel forces without denial.
This lady expresses the cinematographic and cultural/historical relevance of this far better, than I.
