what's an OBSCURE film that you love?

hi, everyone. i am wondering… what's an underground/indie/little known film that you really enjoyed? i'm on a mission to expand my watchlist so i am specifically looking for something under the radar. if it's a well-known english-language film, i'd rather not hear abt it cuz i've most likely heard of it, seen it, or added it to my list already.

a good example: '거미숲 (spider forest)' released back in 2004. one of the best films i've ever seen. i feel like this is the type of film david lynch always strove to make. this film affected me in a deeper sense than any of his stories ever could but i'm not trashing him tho. he seemed like a good lad, God rest his soul
