20. Mannix (1967-75)
For eight seasons, detective Joe Mannix (played by Mike Connors) played by his own rules when it came to solving crimes. Someone who hated being told what to do, Mannix routinely operated in atypical fashion when needing to crack a case. The show resonated with many, as the titular character had traits many could relate to (former soldier in the Army). Aside from the actual character itself, Mannix was exhilarating — as he often faced violent challenges by the opposition in the way of physical punishment and weapons. Interestingly enough, this series was produced by the Lucille Ball and Desi Arnaz’s company.
