Alien, Aliens, Psycho, Halloween, the original Nightmare on Elm Street (and #3 Dream Warriors holds a special place in my heart as does The New Nightmare which was a damn cool concept), Phantasm, Evil Dead 1 and 2, Army of Darkness. All are good watches. And, despite having some pretty bad scripts to the films he starred in, I love Kane Hodder as Jason Voorhees. None better.
