Like Chucky, I saw "Halloween" pretty late into life and the slasher formula has never really been a favourite of mine. However, as the grandaddy of the genre, I could still respect it for what it achieved and would inspire later down the road. It still holds up extremely well today, with the performances from everyone involved still as good today as it was then. I have many favourite movies from this period that I can admit time hasn't been too kind too, but this one is still very polished. I'm never nitpicking moments like I tend to do (especially slashers), as Carpenter clearly put a lot of love into it and it shows.
I was going to score it an 8, and then I remembered the soundtrack. When I think of horror themes, it's the classic score from "The Exorcist" and this one right at the top.
