If you don't like Tina, then you don't really understand this franchise
Tina was the perfect counterpart or companion to Jamie. She illustrated the kind of free-spirited character that Jamie wanted to grow into. The end of 4 and beginning of 5 marked a crossroads in Jamie’s life where she began to purge the strict adversarial ways of her foster family, and found her voice again in Tina! Rachel, although she protected Jamie when it was needed, was too rough around the edges and displayed violent authoritarian tendencies. Her macabre head-on truck collision at break-neck speed against an incapacitated Myers (Jamie’s uncle) ultimately was too much traumatic behavior for Jamie to handle from a “real sister.”
Does nobody find it odd that the Carruthers family adopted a known relative of a serial killer? They did it because Rachel was obviously an unappreciative self-involved problem child, and the parents were equally as retaliative!
If you complain about Rachel’s demise… well, stop! You are rooting for the antagonists. We’re supposed to be in *Myers’ head* as seen in the earliest minutes of John Carpenter’s original.
In the script for 5, Rachel got scissors impaled in her mouth and throat and went out like a bitch. Complaints from Cornell are indicative that she, also, didn't understand her character and these films.
To understand the Myers character, who doesn’t speak and rarely shows emotion, a thorough character analysis and deconstruction of his *relatives* and their immediate circle is necessary.
Fun, spirited and imaginative characters like Tommy Doyle, Jamie, Tina, Lynda and Jimmy Lloyd are who interested Michael. He certainly had no bond with Loomis, his shrink. Although a psychopathic killer, he’s actually quite a fun-loving individual and just wants to go home and share the holiday with similar-minded folk. This is very clear, even though the audience would normally find it tough to identify with someone with this level of mental illness or cult programming.
Laurie, despite the sister angle, was no fun, too straightlaced and repressed, and influenced by the Strode family. At Laurie’s crossroads, she embraced her foster family over her own contrary to Jamie.
This is why Michael actually targeted the other babysitting girls first, and much later set up his ultimate prank against Tina Williams in 5. It was also why Jamie Lloyd was incorporated with a higher calling in the druid cult.
Loomis had it all wrong, and was a lousy psychiatrist. Rage didn’t motivate Michael. Loomis was the angry one, and was just projecting and misreading his patient’s deeds. In Michael’s mind, he’s trick-or-treating and having fun. Jamie evoked a tear and demasking from Michael in 5 when she crawled into the tiny coffin in sacrifice. He was touched by this moment of bonding.
