First half (especially the first half hour) is pretty damn great, then it just goes downhill for me. Expected a lot more from the final act, and that cliffhanger-ish ending didn't work for me.
I'll be damned if Sinister wasn't inspired by this.
Aged like a fine wine.
PTA and Yorke could've cooked up something much better than this, but I was mesmerized either way.
