Something that Star Trek: Discovery has thrown up, once again, is all the questions that surround canon. How much of it is really canon canon, how much can be fudged, etc. And so we ask: what change to canon did you hate the most?
I don't hate the War Doctor (John Hurt) as much as his appearance threw into doubt so many things I thought I knew about Doctor Who. My favourite thing in the world, though, is the way that everyone just decided it would do nothing to change the numbering system already established. No one's number was retroactively changed -- Christopher Eccleston is still Nine, David Tennant is still Ten, etc.
But what drives you up the wall about what was changed?
