Two ideas for the 'zine:
'The Script Doctor' - In this proposed section, contributors get to 'fix' the most egregious Old/Nu Who stories with improved endings, scenes or even complete rewrites. In time, this could also encapsulate spin-off media, like the New Adventures, the comics etc.
'Mash-Up Monster of the Month' - Here, a writer makes a case for a monster or monsters from other franchises as being ideal adversaries for the Doctor. The criteria would, of course, be behind-the-sofa terror, ability to massacre mooks/UNIT troops, pathos/gothic horror, a Whovian vibe, near-invincibility and, of course, being the kind of foe who has to be out-thought rather than out-fought.
Examples might include: The Predator, The Blind Dead, The Thing From Another World, The Terminator/Skynet and Doctor Sun from the old Tomb of Dracula comics...
