Top 10 from this decade, in no particular order:
1. The Witch
2. Bone Tomahawk
3. Tucker and Dale vs Evil
4. Evil Dead
5. The Woman in Black
6. Maniac
7. The Void
8. Horns
9. The Cabin in the Woods
10. Sinister
So many more that could've made the list, but these were the first 10 I thought of
I could probably do a top 10 worst too, with The Babadook and It Follows fighting for the top spot!
