Start off with typical Twilight teenage romance sheenanigans
Brutally murder the teenybopper female lead right around the 30 minute mark
The entire rest of the movie can be described as Stir of Echoes as told from the perspective of the ghost
Throw in Marky Mark and a child molester
Lots of creepy What Dreams May Come-esque surreal imagery, including one scene involving a bath tub that's akin to the Pale Man sequence from Pan's Labyrinth
Arbitrarily set the plot in 1970's Pennsylvania
Why didn't I know about this until now?
