This is an easy one because there’s only one good Halloween movie; Rob Zombie’s remake of the original. All the rest; said original, all other remakes and sequels included; are mediocre at best. The worst; Season Of The Witch; is downright atrocious.
I like Michael Myers as a character. His stoic ominous ways make him the quintessential bogeyman; a classic horror movie villain à la Frankenstein; but his legacy has been ruined by vacuous storytelling. Even Zombie’s sequel is a disappointment.
my vote : Halloween
