I've enjoyed it very much on DVD, and have finished it (a lot of the DVD prints are apparently of a 16MM form [subpar picture quality], but that did not affect how much I enjoyed what, to me, was a well-written, well-shot, well-produced and well-acted series [the play's the thing, IOW]). It's well-worth the money, IMO (series, movies, Adam-12 crossover and all).
BTW, has Mike Quigley ever seen the show?
