By that, I mean, what if a series has both movies (and I do mean movies) and TV shows, should they be in both sections, or just one? This can also apply to ones that have books and such as well.
Perfect example: Star Trek; it has several TV series, 10 movies (11th in production), and a couple dozen novels and video games (though they're both mostly considered un-canon, but that's beside the point), among other things.
Star Wars on the other hand, is mostly based around the 6 movies, a ton of books/C-books, and video games. Yes, it also has the one good (IMO) cartoon series, Clone Wars, but that is still only one.
So really, it's a pretty damn difficult choice.
