As a general rule, good horror movies have simple plots. In Halloween, Michael Myers breaks out of a mental asylum to terrorize Haddonfield and hunts Laurie Strode. In The Shining, Jack Torrance is driven insane by the Overlook Hotel. In The Exorcist, Pazuzu possesses Regan MacNeil to take revenge on Father Merrin. There are exceptions to the rule, but A Deadly Legend isn’t one of them.
There’s no one-sentence (and maybe not even one paragraph) that could sum up all that’s going on in A Deadly Legend’s opening. The Huntar Family is on their way to a summer camp by Pilgrim Lake when a ghost appears in front of their car. They swerve, and the father is killed.
