Medieval time setting is the standardfor both. Higher powered supernatural beings with a stake in the outcome is also a shared attribute. Both treat blood loss as no big deal and both thrive on despair when the chips are down. Big swords and a mercenary type attitude are a constant in both.
Basic theme in both shows has hero/heroin on assignment to kill creatures. In both instances the organization/ boss they belong to could easily be considered heartless and evil. Both shows like to depress you by killing characters you like thus giving you that feeling of betrayal by the writers. Oh yeah lets not forget the heavy attention paid to gore so don't watch after eating.
