I always thought JAG was a half way decent show...even with all the technical mistakes. I believe it was on the right side.
That said, on another thread, I said I would like to see a critique of the show by Iraq war veterans. I had one response, but I couldn't tell if it was from a combat vet.
I will provide you with one once my beloved returns from his current TDY.
As for JAG, I concur with your thoughts. It was a long running show, frankly one of the longest running shows depicting the military. When the show was getting it's footing Ollie North through his expertise to the show behind the scenes and sometimes in front of the camera.
Might be interesting to read his comments if he watched the program.
