10 Huge Doctor Who Plot Holes Everyone Overlooks

10. Dalek Caan's Excellent Adventure

Former/current showrunner Russell T Davies was the king of television back in 2008. He had so much rope that nobody seemed to care when he literally pointed out a plot hole in his own episode.

Towards the end of The Stolen Earth, the Tenth Doctor is reunited with his bestest enemy Davros, who is hanging out in a basement with a rather frazzled Dalek Caan.

Here, it's revealed that the emergency temporal shift seen at the end of Evolution of the Daleks whisked Caan directly into the Time War, which greatly surprises the Tenth Doctor, who states "But that's impossible. The entire war is time locked."

The fact that RTD acknowledged this plot hole in the episode's dialogue is probably why everyone overlooks it, but yeah, hang on a minute: entering the Time War was supposed to be impossible, so how did Caan get there?

The only explanation we do get is that Caan "succeeded", which... well, that's not really an explanation is it.

Steven Moffat would later find his own way past the Time War time lock in The Day of the Doctor, but RTD clearly didn't feel it was a big deal back when The Stolen Earth aired.
