Never has a show given so much to the viewer; drama, comedy, suspense, this show is the best thing to happen to television in years. I myself serve in the military and understand what it means to put a uniform on and defend the innocent and helpless. Dennis Leary was already a genius in my book; yet again he tops his past projects. I've read about his cousin (firefighter) passing away in a fire, so it seems that Mr. Leary takes this project very personnel. That desire to do well has enabled him to create the most enjoyable show I've ever seen. I just got my hands on season 2 and have barely done anything else but watch it. Do yourself a favor and tune it next time it airs. You won't be disappointed.
