I'm not sure all genres belong on the 5 star scale, horror included. Was it good? I don't know; maybe. Was it entertaining? Absolutely.
There's a surprising amount of pacing variation (not always for the better but certainly interesting) and variation between action vs suspense horror. There's at least something for everyone. The acting was also quite good throughout. I enjoyed the subtle depart from our universes rules, it was fun.
Would I recommend it? If you've seen enough horror and want another one then yes. If you're looking for a general movie recommendation then no. It's a fun horror.
