A general adaptation would work too.

No one's gonna argue about a Bond movie or a Men in Black movie that doesn't focus on J and K.

Unless we totally askew something, but we don't need to argue about it OOCly. However, like Traveler said, making something people would have problems with in terms of how the material is interpreted would be good IC fuel for tension and drama, as long as we're all cool with it.

And I also agree with what he said about material that we don't all know about.
