Not stating quality, just personal preference. The only real order here are the first three positions, which really were my three favorite films from 2017. The list order may not match the ratings' ranking.
★★★★★ - Blade Runner 2049, Logan, Three Billboards outside Ebbing Missouri, War for the Planet of the Apes, mother!, A Ghost Story
★★★★½ - Detroit, Gifted
★★★★ - Dunkirk, It
Honorable mentions: It Comes at Night, The Disaster Artist, I Tonya, The Killing of a Sacred Deer, Okja, Wonder Woman, Bingo, The Shape of Water, The Florida Project.
Yet to watch: Phantom Thread, The Post, Mudbound, A Fantastic Woman, Molly's Game, Darkest Hour, All the Money in the World, Columbus and others...
