The Man In Black. Word of God claims that they didn't even know who he should be before the next film was made.
Retconning the twist ending of 4 is seen as this too.
Crowning Moment of Heartwarming: Nurse Patsey trying to do what she can to give Jamie the emotional support and care she has desperately needed, as does Rachel, who seems to have stayed a lot closer to Jamie than their parents did since last year.
A lot people think that Jamie is the only reason to watch this movie, primarily for Danielle Harris giving a great performance and the fact she doesn't actually do anything obnoxious.
Likewise a lot of fans were furious at Rachel getting killed off, claiming she would have made a better protagonist than Tina.
Narm: Jamie screams out "Cookie Woman!" after having a vision of Tina in trouble. The line wouldn't be narm, but it's the fact Dr. Loomis, being half-crazed, is pretty much forcing Jamie into screaming out where Tina is, leading to the Cookie Woman line.
A lot of fans generally consider Michael's crying to be a Villain Decay moment. The viewpoint being that Michael crying kills the scary aura of him and the original concept of Michael being pure evil .
Narm Charm: It should be noted that Donald Pleasence's confused delivery of "Cookie Woman... Cookie Woman???" is the best line in the film.
Replacement Scrappy: Tina gets this for being the protagonist instead of Rachel, who gets killed off early on.
The Scrappy: Spitz, Mikey, Samantha, Billy, the two comic relief Cops.... Really, it's just a cast full of Scrappies. Thankfully they all die by the end of the movie, except for Billy (who's mercifully the least offensive of them).
Signature Scene: The only other reason to watch this movie besides Danielle Harris's performance is to see Loomis take Michael down. Even vocal detractors loved it. Loomis traps Michael in a net, shoots him with tranq darts, and then proceeds to wail on him with a 2x4. Even a stroke can't stop the Badass Grandpa.
Tearjerker: Though the scene where Michael is called uncle, sheds a tear, takes off his mask, and reels back in shame when Jamie tries to touch him could be considered narm, consider this; Michael may be FAR from sympathetic, but it seemed that there was at least some bit of humanity in his heart. Considering that he never openly takes any joy in killing (just pure emotionless killing, with some sinister tendencies), this implies that Michael is a slave to evil. A disease that can never, EVER be cured. And for a moment...he knew this.
The Peek-A-Boo Corpse in the attic. As if Jamie hadn't been through enough up to that point.
