Halloween's supernatural spooky theme is one of the many reasons why I love it, have been into that kind of stuff since I was little, I always thought it was cool es heck (as easily scared I was then, nonetheless
).
I would watch Halloween specials with my family every year but I didn't really get into the Horror and Slasher genre until one year where I got a glimpse of the final scene of Halloween (1978). A few years after that I finally got to see the full film and began to get into it.
I've become a bit more familiar with the Halloween Franchise since then, as well as Friday the 13th, Scream and the Texas Chainsaw Massacre franchises as well.
I also saw another somewhat old Horror film called Pumpkinhead (and it's sequel) for the first time earlier this year, watched it again this October.
