I really don't recommend this movie. I generally really enjoy horror, even some of the sillier plots, but this one was just bad (Not Hereditary bad, but still pretty bad). I'll try not to spoil anything here but these are my impressions.
-Not a horror movie... more like a supernatural thriller that should have been a late-season episode of X Files.
-We all saw the "big reveal" coming from a mile away... and it's the least interesting route this film could have taken.
-The people have no idea how anything in the world works. Period... Nothing works the way it does in this movie.
-The sister, detective, and CSI girl are the only really likeable characters.
-The monster isn't scary, it's powers make no sense, they show way too much of it way too soon, and the creature effects get worse and worse every time they show the monster.
-There is no reason to explain the main character suddenly learning how to control her "powers" at the end.
-So much stupid just to force horror themed moments.
-"eerrr! Super strength! For... uh reasons!"
-"eeerrr! Bullet dodging... for... uh... reasons!"
