The Best Shows About Crime-Fighting Duos
Some of the best TV crime series are about a crime-fighting duo, because it's always more fun to watch a "dynamic duo" than a single super sleuth. The relationship between the inseparable pair is the most important part of shows that feature tag-team crime fighters - their relationship informs how the rest of the show will function and how the crimes will (or won't) be solved. This list of crime-fighting duo shows is ranked from the best to the worst, based on votes from the Ranker community. What are the absolute best TV spin-offs?
Whether the duo is made up of police partners, like Psych, or detective couples (or will-they-won't-they couples) like Lucifer, the satisfaction of a good procedural is heightened by their interpersonal chemistry. Shows like Supernatural wouldn't be nearly as fun if the central sleuths weren't a pair of crime-fighters who are handling their relationship while also saving the world.
 This list features the top shows about crime-fighting duos, ranked by your votes. So, what are television's best crime-fighting duo series? Vote up the detective partner series you think are the best and see where your favorites rank.
