Doctor Who: 10 Things That Must Happen In Series 10

10. A Fun-Loving, Uncomplicated TARDIS Team

The dynamic of the two central stars of Doctor Who - the Doctor and his companion - is a huge part of the series' core appeal. The usual - and best - way to handle it is to show the pair having a blast as they travel around the cosmos. That way the viewer feels like the lucky guest who has been invited on this trip of a lifetime with them.

In the last two seasons, though, things got quite complicated in the TARDIS. First of all, back in 2014's Series 8, Clara and the Twelfth Doctor's friendship was heavily strained due to his abrasive new regeneration and her being caught between her romance with Danny and her life as a time traveller.

In Series 9, the pair were firmer friends again but Clara's increasing overconfidence and Doctor-y demeanour again put them at odds. Eventually, their friendship was portrayed as a self-destructive one - apparently they could even destroy the universe if they continued to stay together (see the Hybrid story arc).

With the introduction of Pearl Mackie's Bill, we would really like to see a simple yet satisfying fun-loving friendship between the Doctor and his companion - maybe something like that of the Tenth Doctor and Donna back in Series 4?
