Doctor Who: 10 Things That Make NO Sense In The Modern Series

Human Nature and The Family Of Blood is one of the best Tenth Doctor stories ever, but its entire premise falls apart once you start to scrutinise it.

The plot kicks off with the Doctor being chased down by the Family, a group of aliens who are thirsty for immortality, and believe that the Doctor can help them achieve it. So, in order to evade them, the Doctor disguises himself as a human, living in a small village in the early 1900s, and becoming a teacher at a nearby school.

But this doesn't stop the Family from tracking him down, and when they do, they wreak havoc throughout the village, killing many innocent people in the process. This forces the Doctor to come out of hiding and take them down, which he does... in about one minute flat. Literally.

So why didn't he just do this at the start of the story?

The episode tells us that the Doctor was simply being "kind" to the Family by not unleashing justice upon them, but this is one hell of a flimsy excuse considering that the Doctor isn't kind to the many, many other aliens he defeats on a regular basis.

Considering how easy it was for the Doctor to beat the Family, he really should've done so a lot sooner. Instead, he put a load of innocent people in harm's way, while also forcing Martha to fend for herself in an unpleasant environment. Not his finest moment.
