10 Doctor Who Controversies Fans Can't Agree On

First introduced in Blink (that one episode of Doctor Who even your cool friends have seen), these terrifying stone assassins made such an impact that it’s no surprise Grand Moff Steven bought them back pronto once he had the big boy chair.

Unfortunately, that’s where, according to some, it started to fall apart.

Any image of an Angel could now become an Angel – okay, fair enough. An interesting addition that was utilised quite well, but more rules kept coming. The Angels didn’t attack if they thought they were observed (even if they weren’t), and on top of this, they now don’t always send you back in time – they can also snap your neck, rip out your vocal chords, and use them to reanimate your disembodied voice. Very metal, but ultimately far less interesting.

And there are contradictions too. The Time of Angels' ‘two heads’ twist hinges on the fact the Angels have a fixed form, but in The Angels Take Manhattan, we see baby cherub angels and a Statue of Liberty Angel, the latter of which somehow manages to cross a city without being observed.

But Moffat also broke the biggest rule of all – he let us see the Angels move. The Angels have always been a fourth-wall breaking villain in that, if the audience observes them, they are also frozen. So quite what the thinking behind this movement scene was, we haven't a clue.

OUR VERDICT: Simple and mysterious was better. The Moff giveth, the Moff taketh away. On their day though, the Angels are still quite terrifying.
