I never thought of myself as a fan of cop shows...but, by golly, now that I think of it, I guess I love a lot of them!
My earliest cop show memories are of DRAGNET, MOD SQUAD, THE FBI, and ADAM 12.
Having seen them more recently, I have to say I still love DRAGNET and ADAM-12...not so much THE FBI. MOD SQUAD I shall shortly find out about as it is now on DVD.
As they have been trickling out onto DVD I have had opportunities to see many episodes of vintage shows like M-SQUAD (love), FEDERAL MEN (love, love), RACKET SQUAD (love), HIGHWAY PATROL (hmmm...it's Ok sometimes), STATE TROOPER (it's Ok), and PUBLIC DEFENDER (love, love).
I have about 40 or so episodes of BOSTON BLACKIE on DVD, but have only watched 2 episodes so far, and not enought to decide if I like it a lot or just a little bit.
