Congrats to Cinemonster for ten years of Hooptober. That's a decade of bringing people together through the act of scaring ourselves stupid.
For what it's worth, I've been Hooptobering for four of those years. Over that time, I've never managed to get in all 31 reviews but I've had a lot of fun and discovered movies I wouldn't have seen otherwise. Will this be the year I finally fulfill my quota? Will it hell.
Anyways, here's the main list with all the rules. Check the notes for how these films fit in.
