Halloween night 1963, six-year-old Michael Myers kills his older sister with a large knife. Why? Because he's pure-fucking-evil. He's sent off to a insane asylum and does nothing, but stare at the wall. Then 15 years later, right before Halloween he busts out and heads straight back to his hometown to raise some fucking Hell.
Unlike Jason who literally kills everybody he sees, Michael is a little bit more thoughtful and only kills those he deems unworthy of being alive. Exactly what this criteria is, I'm not sure, but I think it has something to do with being friends with Jamie Lee Curtis (her role in his life is explained in Part 2) and/or being in possession of something he wants. Anyway, Jamie is babysitting some local kids and hanging out with her friends when Michael crashes the party and starts killing people. Sounds exciting, but it's actually pretty slow going as far as the actual violence goes. Where HALLOWEEN shines is the slow-boiling tension.
Even though I love the film I don't think HALLOWEEN has fared as well over time as other horror films of the 70's. TEXAS CHAINSAW MASSACRE would be the best example of this. If you were to have a double-feature of TCM and HALLOWEEN to a bunch of first time viewers I think TCM would still get a lot of scares whereas HALLOWEEN would probably get a lot of yawns, because it's based more on a Hitchcock kind of suspense with only minimal blood and zero gore instead of an actual attack on the audience.That's just my worthless two cents.
HALLOWEEN is a landmark in cinema history and I still love watching it. I think Michael is a great villain and outside of Part 2 he's never really, even to this day, given the respect he deserves. Jason at least had 4 excellent movies before Hollywood decided to shit all over his character. Michael wasn't so lucky. Maybe one day a savior will come along a resurrect the HALLOWEEN franchise to the level it deserves, but I'm not holding my breath.
