Query: Nostalgia for the Good Guys

I came of age with this movie. Learned to trust myself being the only good guy (even "saint") among the many bad guys. Pacino may be remembered by many as the cool-head, cold-blooded gangster of Godfather series, but as Serpico he remains my hero as the uncompromising, opera-loving, ballet-dancing, intellectual (also womanizer) who "fixed" the corrupt system.
