Who the fuck keeps downvoting all our shit? Who downvotes Forrest Gump?? Fucking simpletons
Forrest Gump was just corny nostalgia porn cashing in on Baby Boomers, it wasn't anything special.
Paris - When it Sizzles. It's a lot of people's least favourite Audrey Hepburn movie, but I think it was the most perfect romcom ever made.
Woman in the Dunes. The lighting and feels. I think I could watch Kurosawa period dramas with more frequency, but I still hold Teshigahara's films in a higher regard.
Blue Spring (Aoi Haru). There have been scores of Japanese films with the same subject matter, but Blue Spring was perfection. The only good time-lapse you'll ever see in a feature-length. Plus, Thee Michelle Gun Elephant did the score, which accompanies the movie perfectly.
Contemporary North American:
Primer. Steeped in esoteric dialogue, you're really not sure if you're just not following or if the writers were just bull-shittin', but considering it's about time travel, it adds to the film's effect. Made on something like $8k and with only ~5m of film cut from the final, it's just impressive.
Animation is a tough one. As far as adult-oriented goes, I'd say Ghost in the Shell. Youth-oriented, probably Howl's Moving Castle.
