Great writing. Good acting, including a few choice scenes with Matt Frewer (I wish he got more roles.) A story that absolutely keeps you guessing. And just enough gore to really sell the horror without going over the top.
Basic story without any spoiler: Guy finds book. Book is bad magic. Bad things happen. You can’t turn away.
So much fun to watch! So do yourself a favor and don’t read about it, don’t watch a trailer. Just go buy it. You’ll thank me.
