Det. Marty Hart and Rust Cohle (Woody Harrelson and Matthew McConaughey, True Detective
The partnership between the Louisiana detectives is a rocky one given that both men have personal demons that can affect the investigation of a ritualistic murder. Marty may seem like the man with it all, but he's hiding a huge secret, and Rust is a nihilistic alcoholic with a propensity to spout cryptic phrases that aren't exactly warm and fuzzy bonding material. Somehow though, it's that very humanity in these fallible, head-butting partners that win out in the end in the face of horrifying circumstances.
