Just cos I'm SO EXCITED about Doctor Who, for the next week I'm going to try and post a Doctor Who-related Top 10 every day until the BIG DAY!!!!!!!!
Today, Top 10 Cliches, in no particular order...

1. Two alien races at war with each other.

2. Alien holiday planet

3. Meeting a famous historical figure

4. Aliens that are not what they seem eg. ghosts that are actually aliens, werewolves that are actually aliens, witches that are actually aliens...

5. Daleks (but they still rule)

6. Death in general

7. A random innocent accidentally discovering the aliens and getting killed before the show actually starts

8. Alien possesion

9. Cliffhangers where the Doctor or companion is faced with advancing aliens and the companion screams

10. Aliens that look like animals
