Spawn
After being murdered by corrupt colleagues in a covert government agency, Al Simmons makes a pact with the devil to be resurrected to see his beloved wife Wanda. In exchange for his return to Earth, Simmons agrees to lead Hell's Army in the destruction of mankind.
Spawn is primarily a dark superhero/action film with supernatural/demonic imagery; horror elements are meaningful and mood-setting, but the core identity centers on action, anti-hero themes, and fantasy rather than being fundamentally horror-driven.
Best for viewers looking for a scary horror movie.
