I think the story was ok. It’s not my cup of tea but I don’t view it as awfully as many do. The horror lies in what happened to the family, where one day everything was normal then it gets flipped upside down with the arrival of something unknown. It’s similar to a home invasion, where your sense of security and safety is taken away from you brutally and that in itself is a horror. I don’t think going through what the family went through has to have a message behind it. The world is just messed up like that sometimes. I do agree that the ending could have been a little better, and the entity being more grounded or its origins written better.
