There's probably a good story here trying to get out but this isn't it

Rating: 3/10 (18 March 2018)

It's more horror/Sci Fi than fantasy/drama and had it had that appellation I wouldn't have watched it.
The conceit is interesting, ALMOST enough to make it worth watching but not quite.
Not read the novel but writer/director is usually a warning sign.
Nice acting and reasonable effects but poor story line development and the beginning (after which it goes - yawn! - into flashbacks) tells you where it's going anyway. The ending is abysmal.
