It kind of is a secret:

My wife didn't like the show when it came out. She wasn't a fan of Denis Leary as a comedian, so it was a hard sell. But over the years she's really come to like
Rescue Me -- which is really a longer, more dramatic version of the denser, funnier
The Job.
After watching all the DVDs just recently, she thought it was hilarious. Too smart and challenging for network television, which is why it got canned. (9/11 didn't help either -- which ironically enabled the show to live on as
Rescue Me on cable.)
The head writers are Leary and the guy who also wrote
The Larry Sanders Show in addition to
Rescue Me. The
Larry Sanders Show being everything that succeeded where
Curb Your Enthusiasm failed miserably (Martin can back me up on that
