The Jamie/Thorn Trilogy is the most "Halloween spirited" out of the franchise?
I'm biased and I am weird because I like 4, 5, and 6 (producer's cut) the best out of the franchise. I also do like Rob Zombie's Halloween 2. My first exposure to the Halloween franchise was Halloween 4 and Halloween 5, since AMC replays them so much during October. I did not grow up watching the original Halloween.
So, the whole idea of the "thorn" rune. There's two names for it: "thorn" and "thurisaz". Thurisaz refers more to an etymology meaning "giant". But thorn refers to thorn, as in pricks and needles that grow out of the ground. I find that interesting, that Michael's power comes from thorn in this timeline because that does go in line concerning Samhain/Halloween.
Halloween/Samhain represents the end of "harvesting" or collecting the fruits of the land. When we collect our fruits of the ground, we find that not everything is exactly fruitful. Some fruits/plants are guarded by thorns. The ground supports the living (fruit), but it also supports the dead (thorns).
