Na Na Na Na, Hey Hey Hey, Goodbye
During the climactic sequence (and closing credits) when Frank takes out Leo and his gang, does the music remind anyone else of a slow version of the oldies song "Kiss Him Goodbye"? This would be most apropos, considering Frank is indeed saying goodbye to his hopes of a better life as well as to the mess with Leo. Do you think Michael Mann/Tangerine Dream were subtly alluding to this with the music?
To see the only real monster, one must only look in the mirror.
