These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
Complete Monster: Michael Myers, a cold-blooded Serial Killer with a hatred of teenage sexuality and a fondness for carving knives. After killing his sister at the age of six, Michael breaks out of prison as an adult and goes on a killing spree through his hometown of Haddonfield, on his way to kill his surviving sister, murdering three of her friends before targeting her. He's stopped, but the horror doesn't end there. Michael returns repeatedly, making numerous attempts on Laurie, her daughter Jaime, and anybody else who gets in his way. Incapable of feeling empathy, and driven by a loathing of seemingly everybody he encounters, the unstoppable and perpetually silent Michael helped to define the Slasher Movie as we know it, and remains one of the most bone-chillingly evil.
Evil Is Sexy: When he's unmasked, Michael is surprisingly attractive.
Seinfeld Is Unfunny: Even though Michael Myers came first, in the later sequels, he ends up seeming like a rip-off of Jason Voorhees. Also since all the cliches Halloween created (or in some cases popularized) have now become cliches they are no longer frightening.
Special Effect Failure: When Michael smashes one of Marion's car windows, he obviously has a wrench taped to his hand.
