Been putting this off forever because I'm a film buff and own 2000+ movies. No way I can do a Top 10, but here's 20 off the top of my head that I really like (in alphabetical order):
Blind Swordsman: Zatoichi (Zatôichi) - I own all the Zatoichi films and this is my favorite, if (but not) only due to "Beat" Takeshi Kitano.
Capernaum (Capharnaüm) - The only Lebanese film I own and one of two child acting movies I can watch over and over again.
City of God (Cidade de Deus) - Hoodlum kids growing up in Rio slums breathtaking? That and a whole lot more. Yeah, this is the other one.
District 9 - Action sci-fi thriller without over-the-top special effects, which aren't needed when the story is this good.
Eternal Sunshine of the Spotless Mind - A Jim Carrey movie among my favorites? Can't take him in anything else, but this one is so good.
Handmaiden (Ah-ga-ssi) - So many great Korean movies, but this one stands out. Nuff said. Not giving anything away.
House of Games - David Mamet at his best. Never trust a con man. Duh
Incendies - Denis Villeneuve (Sicario, Arrival, Blade Runner 2049) films are amazing and this is my favorite (at least until I see Dune later this year).
The Nest (Nid De Guepes) - Best action/suspense film ever? You bet! Samy Naceri at his best.
Nine Queens (Nueve Reinas) - Argentine thriller with twists and turns that actually make sense and you don't see coming.
Oldboy (Oldeuboi) - BRUTAL! But so good. Warning - stay away from the remake.
Once Upon a Time in the West (C'era una volta il West) - Although quite a long saga, no finer Sergio Leone spaghetti western (The Good the Bad and the Ugly, A Fistful of Dollars, For a Few Dollars More).
Our Lady of the Assassins (La virgen de los sicarios) - Gay teen Colombian assassins might be too much for many, but so engrossing.
Parasite (Gisaengchung) - Too many great Korean movies, but this one rules!
Raging Bull - So many great collaborations (Mean Streets, Taxi Driver, King of Comedy, Goodfellas, Casino, etc.), but this is Scorsese's and De Niro's best.
Requiem for a Dream - Best drug addiction film of all time and easier to re-watch than Trainspotting.
Roma - Alfonso Cuarón's (Gravity, Y Tu Mamá También) love letter to Mexico City, even though technically only one neighbourhood. Too slow for many.
To Live (Ikiru) - I love Kurosawa (Rashomon, Seven Samurai, Throne of Blood, Hidden Fortress, Bad Sleep Well, Yojimbo, Sanjuro, High and Low, Red Beard, Kagemusha, etc.), but Ran is overrated and this one is so underrated.
Twilight Samurai (Tasogare Seibei) - Not what you would expect from a feudal Japan era samurai film, but my favorite by quite a margin.
Wings of Desire (Der Himmel über Berlin) - Never had a feeling like leaving the theater after this one. Wim Wenders and Bruno Ganz at their best. Peter Falk isn't bad either, even though he's playing himself. German cinema isn't for everyone.

Too much for most of you to read and much more than I planned on writing, but maybe there's one or two other film nuts like myself in this community that appreciate what occupies my time when I'm not out and about or watching sports. And yes, I did mention Raging Bull, The Godfather and Clockwork Orange, but no Shawshank Redemption, Schindler's List, Citizen Kane, etc.
