While I do understand that the novel and film/TV/OVA/games are often at odds, I have noticed that sometimes the multiple pages are actually counterproductive, especially when these are things that both have in common.
Take as an example the Earth articles; do we really need Earth (film) and Earth (Novel)? Why not make a single Earth (planet) article and point out any discrepancies between versions in sub-sections? That way we can consolidate knowledge in a single easy-to-use resource without worrying about missing some important bit of knowledge that is mentioned only in the Earth (obscure magazine short story) article.
Another example; the Queen Bug; really, do we need to have three articles for what is essentially the same type of creature? If push comes to shove, one could always make a "master" article and (if the differences are particularly significant), secondary articles for the deviant version.
Following this standard, it should be easier to fully categorize articles so that those interested ONLY in the novel/film/tv/ova/comics/RPG version can focus on these while the other articles lose relevance.
