I think the movies do a reasonably good job of it. At least a large amount of the material he's using to supplement the Hobbit movies is from other works of Tolkein, if not The Hobbit itself.

Scouring of the shire.

I don't think mixing the Hobbit source material with other middle earth stories is exactly the best route to go in hindsight (LOTR and its appendices work better though). And isn't Evangeline Lilly's character in the Desolation of Smaug a completely made up person that never existed in Tolkien's books?
