I thought it was pretty funny, although a bit raw in the language department. That part doesn't surprise me all that much since Denis Leary is involved. I loved Rescue Me so it was an instant season pass once it showed up in the guide. I just wish they could figure out some way to bring Lou back from the dead and inject him into this series.
FYI - The wife bailed on it after about 90 seconds so if you've got tender ears you might want to avoid this one.
