For me it has to be Miami Vice. I've been addicted to it since I was a kid watching it with my Dad in the 80's. I've checked out other police/crime dramas on TV but none could compare to this show. I still watch it to this day. The ups, downs, and tragedies that Crockett and Tubbs went through on the show both personally and on the job were very captivating. Also the style of the show, the cars, the music... it was just awesome. What's yours?
