See, I wouldn't even do that. I'd just write a base-primer for what the show is about, with pictorial references. Then, if someone else wanted to add what's been happening by season, that's cool too. But, all that's really needed is the main core idea of what the show is about...
it's about a bloke in a phone box flying around in time and space, usually with a fit bird in tow, fighting aliens. and sometimes he changes his appearance.
