Epic fan theory
Philip Sandifer, explaining the most nuts and yet weirdly awesome theory about Who I’ve ever heard. His re-watch blog, [the TARDIS Eruditorum](http://www.eruditorumpress.com/blog/author/phil/tardis-eruditorum/), is very much worth a read, if like me you’re a total nerd.As for me, my favorite epic theory about Doctor Who remains that Graeme Harper and Robert Holmes are both, as ‘The Brain of Morbius’ suggests, pre-Hartnell Doctors, and that the making of 'The Caves of Androzani’ is itself a multi-Doctor story that explains how the Doctor got around the twelve regeneration limit, namely by sneaking out of the narrative and cheating the rules.
