Please note that this list is in no particular order! It's not a ranking, nor organized by genre, et cetera. It's just a running list of the movies I've enjoyed over the years.
Alien - Quite possibly my favorite movie of all time.
The Tale of Zatoichi - A classic series. There are over 26 titles for the Zatoichi series but this is the original. Don't miss if you enjoy samurai movies.
Yojimbo - Akira Kurosawa at his best. My favorite samurai movie ever made.
The Descent - In a sea of underwhelming horror movies, this one did not disappoint. Claustophobic and intense.
Spirited Away - A masterpiece. Hayao Miyazaki's imagination is a gift to all of us.
The Last Starfighter - Pure 80's nostalgia.
Memento - Confusing in the best way possible. It's rare when a movie really pulls you in directions that feel as real as this one.
Dark City - Wonderfully dark and weird. The cinematics are amazing, and feel like a whole another world.
Nightcrawler - Intense. A foot on the gas the entire duration of the film and dripping with sardonic tones.
Oldboy - Won't give this one away. Not for the squeamish but a must watch.
Pan's Labryinth - Brutal and beautiful. Please don't watch any dubbed versions.
Parasite - So good. The awards won are well deserved. Funny, tense, and shocking blended into a engrossing story.
Shawshank Redemption - A great film. One of those rare movies that I can start watching from just about any point in and still enjoy.
Pans Labryinth - An amazing blend of historical fiction and fantasy. It is visceral and dripping with imagination. My favorite from Guillermo del Toro.
Akira - To this day, some of the most breathtaking animation you'll ever see. A friend in high school let me borrow his VHS copy and I was immediately in awe. My first real anime I recall, and one that may still be unmatched overall. Visceral, violent, strange, and amazing.
