It seems appropriate somehow that a series that was, in part, born out of the aftermath of 9/11 ends the week of that tragedy's tenth anniversary. When it premiered in 2004, Denis Leary and Peter Tolan's firehouse drama was hailed as a bold, provocative series that, along with The Shield, cemented FX's reputation as a destination for risk-taking shows. And even though Rescue Me's quality (as well as its ratings) dipped over the years, it still took bold chances and generally gave its sizeable cast compelling material to play.
