As you can tell from the headline, I've rewatched this show a number of times and it never gets old, even the smallest things like where they filmed where impeccable! the first time I watched it I couldn't tell who the murderer was, and I kept flip flopping but after rewatching it the signs were there. those small details combined with amazing giant ones is what really makes a show. I know I sound easily impressed but goodness! it just couldn't be better! 10/10 would recommend its now one of my favourite shows ever!
