I used to watch this with my mom who was a retired police officer and she said no other show nailed the reality better than this one. The stories and characters were handled so well and never one dimensional. I laughed, I cried, I was left with an impact. The fact that there were real firemen and officers in the show definitely shone through. I can't believe it only lasted 6 seasons, I'd still be watching it if it were on. Of all the shows that deserve a revival, this one is the most. So glad I found all seasons on Roku, in case you're looking for it.
