I think this film took a bit longer to get going, at least it felt that way.
The last 15 or so minutes are very good.
One of my big gripes was:
I don't have a problem with the kids calling the demon Toby. It is after all how a child is relating to the "imaginary friend". I mean if the child is going,"this is my imaginary friend Bloody Demon" then a parent is going to being having their child tested. Normalcy breaks down faster than "Toby" needs.
Overall I still enjoyed the film though.
I'm thinking B/B- as a grade for now, may change, we'll see.
