I would have liked to have seen more discussion on this before it was closed, particularly how OC#SMALL does or does not apply, there was no decisive argumentation on that point.  I'm a little annoyed it was you who closed the discussion when you're someone who has nominated the same type of category for deletion yourself.  And now if someone is looking for articles on e.g. sci-fi film series by genre, they won't find the Class of Nuke 'Em High film series, because the category was deleted and there's no Class of Nuke 'Em High film series article.  One could create an article for it, but I don't suppose it would have much content unless someone were really motivated; the categories didn't require anyone to create good articles, just links.  Grumble.  What would you suggest?  Creating a film series article?  Putting just the first article in the series in Science fiction films by series?
