I'd say it's in my top 5 greatest films, up there with Pulp Fiction and Taxi Driver. I'd recommend anyone watch this. Although, it's the most realistic depiction of heroin addiction I've ever seen in a movie, it's also great in several other ways, writing, cinematography, music, etc.

Of course, I'd have one more shot.

. . . and I wouldn't suggest watching this scene unless you've watched the movie. It's one of the most emotional endings to any movie I've ever seen.
