- Doctor Who is a long running TV Series with no spin-offs or reboots to interupt continuity.
Doctor Who had that gap between 1989 and 2005, I realize that 16 years isn't 34 (85 to 2019) but it's still significant enough to serve as a decent example.
the section you refer to has things which aren't necessarily errors.
For example: Scrappy being cut out of a flash back might represent characters not remembering him, or trying not to think of him.
Vincent missing 2 ghosts might simply be a memory problem too.
I'm not going to go through all of them to explain stuff like that, I'd like if you could perhaps prioritize a "top three" or something which you don't think can be explained away.
