It's probably one of the top 10 movies ever made. If you argued top 5, I'd listen.
I always wondered what it would have been like watching this after I had seen a lot of movies instead of it being one of the first movies I can remember falling in love with. Maybe I wouldn't have underrated it as much. We were kind of spoiled by Pulp Fiction. Nobody before us had seen anything like it, but to us, it was just a cool movie. It isn't until now, after we've watched tons of other movies, past, present and future, that we finally understand how gotdamn good this movie is. I can probably recite every line of this movie. From "I seen em do it, man, they fucking drown 'em in that shit." to "Now, you got a corpse in the car minus the head in the garage. Take me to it." I love Pulp Fiction so much that I love From Dusk Til Dawn just because of the tiny bit of similarities they share.
This movie is kind of what keeps cinema fresh. You could almost judge movies before Pulp Fiction and after. The artform changed when this was made.
It always cracked me up how Sam Jackson has the jheri curls in the movie, but in almost every piece of promotional material I ever saw for it he had short hair.
