To throw my own hat in the ring, I'd highly recommend Peter Strickland's 2012 love letter to Italian giallo cinema, Berberian Sound System, which is truly amazing and brain-warping.
Not mention its exquisite use of sound design and its portrayal of Foley work in the film itself to really heighten the atmosphere to skin-crawling levels. 9/10 for me.
Also, I would also recommend Steven Soderbergh's 1991 Kafka, which really does a good job in bringing the Kafkaesque surreality to life.
Also, speaking of Kafka, Richard Ayoade's The Double is a fantastic interpretation, with a Terry Gilliam dystopian flair, and a talented cast, including Mia Wasikowska & Jesse Eisenberg (who over the years I've come to admire—you just have to realise that he is really good at playing only certain types of roles, and as a result he's essentially only cast for those roles) excelling at the characters that he plays best and given the space to do so.
Thanks for the recommendations @majorx3thom, I will add them all to my watchlist.
