I ended up quite liking this one much more than I thought I was going to. I actually really wanted to give it a 7 but there were two major downfalls that made it so I just couldn't bring myself to do it.
This movie had quite a few factors going for it. It looked quite nice with a generally antmospheric setting and had some awesome sfx and monster makeup. It also did quite a good job at having a slow pace that was tension building and not boring. There were parts that definitely could have been picked up a bit but I was intrigued and engaged throughout the movie.
Another thing I really liked about this movie was the script. I found it quite well written to the point where it stood out to me for the positive, when usually it's the opposite. There were a few clunky/cliche moments but I think that fell much more on delivery than the writing.
One of my two main issues was the acting. Unfortunately it really did not do it for me and I thought it did the movie and script a disservice on multiple fronts. The other thing was its blatant derivative plot. If you have not seen 2016s A Dark Song, it is almost identical. The only problem is... I was not in love with A Dark Song and honestly thought that From Black was more entertaining as a whole. Regardless, the feeling of it being a rip off 7 years later is for sure there.
Despite this, I still had quite a good time with this movie and if they could have done some recasting and sprinkled some originality into the story I think it could have been very successful. Would recommend.
