Apocolypse Now... I might go along with that but then I'm partial to Joseph Conrad- it was the story upon which the movie was based that was the truly brilliant part of it and that was written around the turn of the century.
Blade Runner is pretty good. Once Upon a Time in America is also pretty good. I personally like Blue Velvet but I wouldn't have called it top ten material- unless it was a top ten for weirdness.
Another highly underrated VN movie is "The Siege of Firebase Gloria." Based on a true story, the tactics and action are highly realistic. R. Lee Ermey is the leading character and does this part flawlessly.
