Two of my all time favorite movies, Taxi Driver and Apocalypse Now. Both have many scenes that would fit in this thread.
for Taxi Driver, this is a famous one. I think Scorcese said that he did this dolly shot of Travis on the phone because it felt so pathetic that you couldn’t watch.
Apocalypse Now…well, this is the climax scene but a lot going on visually. I know folks love to hate on The Doors, but The End was the perfect song for the movie and Coppola used it perfectly. Visually, I loved Willard emerging from the water. It’s obviously edited in reverse, but still striking. However, for some reason the shot a few seconds later of him squatting and then standing with the blade in the rain while lightning gives the viewer glimpses of him before the assassination of Kurtz always felt powerful to me. Finally, the quick cuts of Kurtz being killed with the sacrifice of the ox is hardcore, especially since it was a real ox.
