Thanks Simon. I picked up the Blu-ray new for peanuts (£4 I think?) and that will do me. I liked it a lot and it was like a breath of fresh air. I like Midsommer a lot too but the Blu-ray will do for me on that one too.
I was half way through this review before I realised I'd watched it back in June - I'd blanked it from my memory. Dreadful ending; like The Game of Thrones, it destroyed everything that came before it.
