Way too many good films and taste is very much a personal preference in the end, but for me:
Castaway on the Moon (Korean)
City of God (Brazilian)
Y Tu Mamá También (Mexican)
Memories of Murder (Koran)
Martyrs (French)
Drive
The Revenant
Atonement
Inception
Training Day
Special mention of the whole Pusher Trilogy, but since the first one is from 1996, i didnt want to include them.
