Doctor Who Thread III: Reverse the Polarity of the Neutron Flow

[Sunken Valley]

Thu, you know why they are all contemporary and human. they represent us in the whoverse. they get things explained to them so we can understand what's happening, because it's primaraily targeted towards the younger demographics who won't neccicarily understand the complexities of life.

Yes to this. 3 other reasons.

1. It's very difficult to effectively mimic someone from an earlier or later timeline. Sooner or later you'll let some mistake slip and the history buffs will be all over you.
2. An Alien Companion would be accused of being too "humanised". It's not the 80s anymore (the last alien companions were Peter Davidson's Nyssa, Adric and Turlough). You can't get away with giving the alien the same values and personality as a human.
3. Reference Jokes. The Doctor can't make them up unless he has someone who'll get it listening.

Why the companion is often a female and its never been an all boy ensemble on the TARDIS:
1. Doctor Who prides itself on being a gender equal show, not a boy show or a girl show. That way you need a mix of genders. How better to do than make the deuragonist female.
2. If it was all men, the public would scream for gender equality.
3. The companions get themselves into trouble every other episode. The Doctor has to save them. The Doctor looks more heroic doing so if he's rescuing some helpless female. Terrence ***** (writer for Doctors 3 and 4) even said the role of the companion was to be tied up and screaming for the Doctor's aid.
4. Sex Appeal.
