The TVI Take
Alejandro González Iñárritu's 2003 second feature, three interlocking stories told in non-chronological order, anchored by Sean Penn, Naomi Watts, and Benicio del Toro. The structural commitment to letting the fragmented-timeline render the moral architecture of grief and culpability is canonical mid-2000s American-international auteur cinema.
