Read it. Disliked the ending on the movies, because the jarring return to Shire and seeing it... ahem, despoiled, is the real finale for me.
The hobbits were heroes. They'd seen the big world. There could be no return to the old innocence, and so, appropriately, there is no innocence left to return to.
And yet, they'd also learned that adversity can be overcome for a better future. Hence them cleaning house.
Why, oh why, did the movies have to leave it out.
Oh well. Can't have all we want. Still liked the extended versions of the movies and the book series as well.
Silmarillon is something I really would like to like, but it's just too disjointed for me. Too many characters, alien (elven) names - usually two or three for a single object or person and too long timescale.
