The Eight Doctors is, regrettably, the first in the long line of Eighth Doctor Adventures (no, not those ones) and it involves - to absolutely nobody's surprise - eight whole Doctors. It's written by Terrance "Ask Me How I Got This Name" Dicks, who is a pretty cool guy that edited some scripts back when Jesus was a boy. Following in the footsteps of other multi-Doctor stories, some of it's a bit shit, and it also made a lot of educated individuals really angry because it retroactively fucked with a lot of pretty important stories. They really have to stop doing this.
