10 Most Obvious Doctor Who Plot Twists Ever

It's firmly established in The Daemons that what we might perceive as magic is really just science beyond our understanding. This has its roots in sci-fi writer Arthur C. Clarke's famous Three Laws, one of which is that "Any sufficiently advanced technology is indistinguishable from magic."

In Doctor Who this is also true when it comes to supernatural creatures like werewolves and vampires – or at least it used to be, until gods ran riot and goblins kidnapped babies.

Take vampires for instance. The Doctor has encountered multiple blood-sucking aliens like the Plasmavores and the Great Vampires in their travels through time and space. All of them are alien beings with genetics beyond our own understanding, rather than mythological creatures from planet Earth.

So it was painfully obvious that The Vampires of Venice was only ever going to end one way – with the big revelation that the pupils of Rosanna Calvierri's mysterious school were not in fact vampires, but were human females turned into blood-sucking alien Saturnyns.

The inevitable reveal doesn't detract from what is quite a fun knockabout episode that riffs on Hammer horror movies, but you do wonder why the Doctor, Amy, and Rory spend so much time considering the possibility that there's actually something more supernatural going on!

Perhaps the Doctor was so keen on Calvierri's pupils being vampires because he was bored of meeting aliens masquerading as them!
