I was unsure what to make of it prior to watching. So, I thought I'd give it a chance to see if it would grab me or not?
And after watching it - I found it to be quite enjoyable and slightly twisted but this is no bad thing at all in fact it has made me want to watch the next episode. Overall, I'm really happy with this series although I don't see it making it past a second series (if a second one is to be made).
I don't think the writers have it in them to really make series upon series of this show. lets hope i am wrong though.
