I found this movie to be very successful for what it was.
Solid story and the pacing was quite good, kept you on your feet and never got slow. There were a couple of blatant continuity issues that bothered me and I feel like it was lacking a bit in character development and depth. There were a lot of characters in this, but a lot that goes unexplained as far as their background/ intentions go.
Sometimes the special effects looked good and sometimes they really did not, a bit inconsistent on that front. Acting seemed... fine, from what I could tell as an English speaker and it certainly wasn't distracting. Felt like they were setting it up for a sequel, which I would for sure watch and also interested in watching the original.
With all that said, over all I was thoroughly entertained with a solid, quite creepy witch/supernatural/gorefest horror. Would definitely recommend to horror fans.
