The first part of a story should have something that make the main characters likable or something we can identify with.
It is better to invest in a good makeup artist than just bying some cheap contact lenses at Amazon you see at any rave party.
Laughing children with some ketchup stains are not scary. Speaking latin is not scary. Wearing a black hoodie is not scary.
Black goo, can actually be scary, but it have to be in context and with some explanation.
Now there are actually some good nuggets in this mess.
Having 3 bad guys with different objectives is actually a really good one. This would add to the story if their different goals would clash more, how would the stalker react if he saw his lady being sacrificed ?
The house with ghosts repeating their last day as living, is also a good one - if only there were a reason to follow the clues to how that day was and what order it happened in. If the couple had found a diary, some pictures adn so on.
Moaning in a movie must be distinct enough so we understand what the characters hear, and what belongs to the soundtrack. The creaking of the floor in the beginning was very clear and effective, we heard a second creak from the left, and understood there were someone there. Why would this be dropped in the rest of the movie ?
There is more but brings me to the final nail in the coffin for me in regards of this movie, it lacks any subtlety. Any form of building suspense is soon destroyed here with some closeup, wobbling of camera or straight blurry fighting scene.
This might be ok, in your filming of the action in riding the rollercoasters at Disney, last vacation there - but is out of place in a thriller or horror.
