is completely in line with the subjects of the film and their unconventional lifestyles. they don't give a shit about the rules of society, and the film doesn't give a shit about the conventions of filmmaking (hence the multiple/continuous voice-overs, freeze frames, Henry talking directly to the camera, etc..)

someone even brought up in another post how even in the end credits you have Sid Vicious of all people butchering Sinatra's "My Way" (a traditional wise-guy anthem)

also we're really pulled in to Henry's rise and fall. It's nearly impossible to watch the first half of this film and not secretly wish you were in the mafia. it reads as pure celebration of the lifestyle. but as soon as Spider is killed, everything changes drastically. including the viewer's attitude toward the subject matter.

I'm trying to think of something to say about Henry's "Last Day as a Wiseguy" sequence, other than it's one of the most brilliant series of scenes in any movie, ever.
