19) Harper’s Island (2009, CBS)

This show makes every episode feel like a countdown to death. A wedding on a remote island turns into a massacre. The kills are brutal and creative. The scene where a man is split in half by a boat’s propeller is shocking. The mystery keeps you guessing until the end. It is rare for network TV to go this dark. It was ignored because it aired at a time when slasher shows were not popular, but it remains a hidden gem.
