"...If there's one thing I know, you can't control evil. You could lock it up, you could burn it, and bury it, and prays that it dies, but it never will. It just rests for awhile. You could lock your doors and say your prayers, but the evil is out there...waiting. And maybe, just maybe...it's closer than you think."
— Tommy Doyle, opening narration.
Halloween: The Curse of Michael Myers opens with a teenaged Jamie escaping with a baby from the clutches of a mysterious group known as the Cult of Thorn (who freed Michael from jail at the end of the previous film). She doesn't get far — thanks to Michael Myers — but she manages to hide her child before Michael finally kills her. Tommy Doyle, one of the kids Laurie Strode babysat in the original film, finds the child — an act that leads Michael back to Haddonfield. As the bodies start to stack up again, Tommy — assisted by a retired Dr. Loomis — tries to unravel the mystery surrounding the cult that seemingly controls Michael and save the child Michael wants to kill...This film gained infamy due to its two bootlegged alternative versions: the gorier director's cut and the much different producer's cut. This film also marks the end of this version of the Halloween continuity; the next Halloween film — Halloween H20: Twenty Years Later — ignores the events of this film (and the previous two films) and creates an alternate continuity that picks up after the events of Halloween II (1981).
Halloween: The Curse of Michael Myers contains examples of the following tropes:
Abusive Parents: John Strode is all three kinds, physically, verbally, and emotionally.
All Girls Want Bad Boys: In the beginning of the film, a caller on the Barry Sims show says she's in love with Michael because he's so uninhibited and untamed.
Lets also not forget the innocent midwife, who helped Jamie and her baby escape, has her head driven through a conveniently placed wall spike and is left hanging. (Eh-hem, the first kill of the film, mind you).
Jerkass: John Strode and Barry Sims. The former is the abusive father of Kara and Tim, who also gets himself, his wife and Tim killed because he neglected to tell them that their house was where Micheal Myers use to live, and the latter is an obniouxious, rude and sleezy radio DJ who ignores Jamie's cries for help. Needless to say, nobody was upset when Micheal killed both ofthem, with John Strode in particular getting one of the most brutal deaths in the series.
Kill the Cutie: Jamie Lloyd, who winds up impaled on and ripped open by tractor harrows courtesy of Michael.
She may count as an older example but, Debra Strode as well after all she puts up with from her husband.
Mama Bear: Jamie Lloyd and Kara Strode. Jamie is a subversion because Michael still kills her, but still manages to keep her baby out of his hands. Kara takes on shades of Action Girl when she tries to keep Michael from killing Danny.
Mythology Gag: Somewhat. Kara's parents are Debra and John Strode.
Series Continuity Error: The Myers house looks nothing like it did in the first and second films, and definitely nothing like it did in the previous film, where it was practically a mansion. At the time this movie was made, it was on the same continuity as the first two films, so there's no excuse for the glaring discrepancy.
Shoot the Shaggy Dog: After getting mocked for being related to Michael, becoming mute due to a powerful connection with Michael, all her friends, her sister, and her dogs killed, Jamie is kidnapped by the cult of Thorn and is forced to have sex with Michael, and she's finally impaled by farm equipment. Jamie could be the contender for the most depressing character in all of the horror genre.
She literally gets shot to death in the Producer's Cut.
Soft Glass: Probably one of the craziest examples ever happens when Kara flies face first through a window and belly flops to the ground two stories below with no discernible injuries from either the glass or the fall. Honestly, with Made of Iron abilities like that, why the hell is she afraid of Michael Myers?
She most likely remembered to roll.
Spanner in the Works: The midwife throws off the Cult's whole operation simply by helping Jamie escape with her baby. The entire movie hinged on this one act of kindness.
There Is No Kill Like Overkill: A scene has Michael preparing to kill a bunch of sanitarium employees by overlooking a tray filled with medical tools. At first, it looks like he's going to grab a scalpel, but, having apparently gotten tips from Jason Voorhees, he decides to grab a huge machete (that was there for some reason) instead.
It's implied they may have considered Michael the ultimate tool to extend their will, an Implacable Man assassin. And they may have been using Jamie to breed new ones if need be. If killing Michael's relatives helps keep him under their control, so be it.
