Above par horror movie. Tried to be a bit different than its other kinds. Better than most of the horror movies we get to see. There are only a few good horror movies out there, this movie could have ranked well in its genre. Glad this was made, slightly quenched my thirst for a good horror.
Ofc, not giving it a 5-star, because killing everyone mindlessly is questionable, even for a demon. I mean, it's a demon for lord's sake, not a temperamental serial killer. Demons have ethics as well, not to mention limitations and objectives. Demons are not mindless creatures that kill aimlessly.
I won't say ending was lazy, because it really wasn't. The ending gave more twists than the Congo river. While some odd turns were interesting, not all were logical.
The writers didn't miss out any opportunity to give a slight scare. Slowly and surely, the entire movie has scary elements, none of which seem forced. The horror eases in, never get's intense. It's like a soothing horror film.
Looking at the ending, maybe writers didn't want to make a sequel. Understandable. Had potential to be a great movie, stopped at satisfactory.
