10 Doctor Who Cliffhangers That Made You Say WHAT?!

10. The Dalek Fleet (Bad Wolf)

As if Bad Wolf didn’t already have enough going on with the killer Anne-droid, the rather permanent Big Brother evictions, and Captain Jack Harkness pulling a gun from, um, somewhere. On top of all that madness, RTD just had to throw the Daleks into the mix, didn't he?

The revelation at the end of Bad Wolf that the Skaro natives had survived their supposed destruction and it was they who were in control of the Game Station was the first major cliffhanger of modern Doctor Who.

The backstory of Christopher Eccleston’s Ninth Doctor implied that the Daleks were all destroyed during the Time War, so the discovery of an entire Dalek fleet heading towards our heroes was quite the bombshell, both for the Doctor and the audience.

That closing moment where the Doctor defies the Daleks' orders and essentially risks Rose being exterminated was inspiring but also rather risky, and left audiences unsure about whether to applaud his nerve or chastise his recklessness.

It really was a perfect encapsulation of the Ninth Doctor.
