I watched this last night, it was pretty good, perhaps not quite as good as some people have been making out though. It's incredibly dark, like literally there is nothing positive going on in the film at all, all the main characters aren't portrayed in great light. The cast were excellent, especially Oliva Colman, I thought Peter Mullan was very good aswell.

Agreed. The twist was good but I thought there'd be a bit more suspense. Still a good film tho. And Olivia Colman's performance is brilliant indeed. Peter Mullan as always is never disappointing, he can go from heartbreaking to intense in a snap. Imagine him in a film with Ed Harris, the cinema would probably explode!
