“If you’re thinking along the lines of a film as unsettlingly insidious as Suspiria or as artistically eerie as Black Swan because of the similar setting and themes, you’ll find Nocturne isn’t anywhere close with its dialed down darkness.
Nocturne fares a bit better, even though at times it’s an almost blatant rip-off of Black Swan , substituting piano for ballet.
If anything, Nocturne is more indebted to the likes of Darren Aronofsky’s Black Swan, the recent works of Ari Aster, and Damien Chazelle’s Whiplash (which was also produced in part by Jason Blum).
Witness Black Swan , Suspiria and its overlong 2018 remake, the recent gore-fest The Perfection (better known as "that Netflix vomit movie") and even the jazzy Whiplash , which is more of a thriller than a horror flick but still features lots of psychological terror and bodily harm.
Stylishly directed by British first-time feature filmmaker Zu Quirke, Nocturne could perhaps be best described as Raw meets Black Swan .
There are also stylistic influences ( Suspiria especially, but Black Swan and Carrie also come to mind) and creative choices (including a deliberately jarring array of sound cues) that elevate Nocturne above the other “Welcome to the Blumhouse” films—the rest of which are fine but do share a general vibe of being made-for-TV movies, which technically they are.
