It's Prom season again, so we're dressing to the nines, renting a limo, and saving the last dance for "Hello Mary Lou: Prom Night 2". This 1987 sequel about the revenge seeking killer spirit of a dead Prom Queen is one part "Carrie", one part "Nightmare on Elm Street" with a pinch of "The Exorcist". This surprisingly entertaining film features awesome special effects, great kills, mundane items that explode, and the world's worst school principal. A whoop bop a lou bop, a whoop bam boom!
