Firstly, I love this show. However, anyone watching this particular episode who is British or resides in Britain will have spotted that this clearly wasn't filmed in the UK. The overuse of black cabs, the occasional London bus, the misshaped post boxes, blatant green screen backgrounds and misplaced architecture, the non UK cars with unrecognisable license plates. For a show with such great content, this was a real half assed effort, especially for a season finale.
