I think what should be considered is that it is based on the book. So the idea, the premise, of creatures that cause suicides, and the setting of the house, is based based on the author's idea.

After that the entire story is very much left to the liberty of the director because it doesn't compare to the book. The characters are all different and in some cases new.

Whilst I like Sandra Bullock, Malorie is meant to be 24 and never has a relationship with Tom. If you wanted a big name fine but this was badly cast.

The suspense in the book is rarely felt in the film and it's flat and doesn't reflect enough on Malorie's teachings on the children.

The best bit was Tom Hollander's character. Well cast.

Watch if you're curious but prepare for disappointment.
