Don't spend too much time on what was at the moment not meant for adults, like there is alot of other art to look at and interpret. It was more of a don't get crazy into it, my own Dad got super weird into interpreting things he thought he found in Doctor Who. It was both sad and weird. Just maybe don't dwell to much on things people didn't also give much thought to.
I think the existence of enough technical information for such an index to even be possible is what I mean by internal consistency. Not the absence of plot-holes or ret-cons.
Doctor Who is the opposite of Star Trek. It makes little attempt at internal consistency. It helps that time travel plays a large part in it. That said, it's been unwatchable for quite a while.
