Gays gone wild.
I'm not sure why I bothered to watch the original Cabinet of Dr. Caligari in preparation for this, because the two really have nothing in common beside the namesake and the unhinged production design.
There's really nothing I could say that could prepare a person for something like this. It's pure, unfettered madness; camp that's so self aware it warps its way around into an off-kilter sense of reality where perversion reigns supreme and kinks physically manifest in this psychosexual Cronenbergian nightmare.
You are not ready.
