The best serial cop dramas of all time include long-running police television shows that managed to combine elements of mystery and suspense, captivating viewers along the way. TV cop dramas have long been a major part of American television (with many ranking among the best TV shows of recent momory), and they've remained popular for decades. This list includes some of the greatest police TV dramas ever, but if you know of a particularly good one that's missing, feel free to add it. And be sure to vote for your favorites, and vote down any programs you really didn't like.
A truly great television cop drama combines interesting, unique story lines with fast-paced action and a solid script. Having an extraordinarily strong ensemble cast doesn't hurt, either. What's the best cop show ever on TV? Many fans will argue that it's the brilliant, David Simon-created HBO drama 'The Wire.' Others might maintain that the FX drama 'The Shield,' which starred Michael Chiklis, is the greatest of all time. And, love them or hate them, it's hard to deny that the 'Law & Order' franchise programs are almost always solid choices, too.
Older, classic serial cop dramas are also included on this list, because they paved the way for more modern police procedurals. Among them: The ABC crime drama 'The Untouchables' (1959 to 1963) and the long-running classic 'Dragnet.' And of course, no list of the best serial cop dramas ever would be complete without 'Columbo,' which starred the late, great Peter Falk as homicide detective Lt. Frank Columbo.
Hopefully everyone will find at least one or two favorites among these fantastic serial cop dramas, but if not, remember: You can always add your favorite cop drama, and you can rerank this list your way!
