Arbor Day (1990)

Forget the gentle holiday—this is a slasher rooted in trauma and twisted symbolism. *Arbor Day* transforms a childhood tragedy into a brutal, gardening-themed revenge spree that’s as creative as it is unsettling. The emotional hook lies in Elmer’s 20-year catatonia and the cruel system that breaks him, making his violent awakening both tragic and terrifying. If you love inventive kills, a psychologically wounded villain, and the classic “teens in the wrong place” setup, this film offers a fresh, grim harvest of horror that lingers like a snapped branch.
