One more mention for Dark, absolutely the best thing on Netflix IMO.
Others:
Neuvas Rienas (9 queens) - an excellent Argentinian heist/scam film with quite a cool look. Like a mix of Ocean’s Eleven (plotwise) and the Bourne films (visually).
Intacto - interesting Spanish movie about people who are able to steal others’ luck. I could imagine Christopher Nolan doing an English language remake.
Le Havre - fun French film about an old man helping shelter a child who is in the country illegally. Very funny.
Akira - obviously
Ringu - original Japanese version. Terrifying.
Crouching Tiger, Hidden Dragon - quite an obvious choice, but it absolutely blew me away when it came out.
The Killing - Danish TV show. Not seen the American remake, but the original is amazing
Oldboy - Korean movie, as above, remade, but I’ve only seen this. I suspect this one is better!
Godzilla Minus One - monsters! And the suffering of post WW2 Japan! Odd mix, but it works!
8 Femmes - very funny French murder mystery. Recently remade (pretty well) in Italian as 7 Women and a Murder.
Duet for Cannibals - very strange Swedish film I saw recently about two couples and some strange living/working arrangements.
Rashomon - classic Japanese movie, where we see the same event from 3 different perspectives
Taxi - brilliant French heist/crime/driving movie, with some superb car chases
