Exploring the People of Middle-earth: Lobelia Sackville-Baggins, an Unexpected Hero.

… Lobelia is one of only a few Hobbit women who are given more than a momentary glance in Middle-earth, and a compelling character in her own right. And what’s more, her narrative arc illustrates beautifully some of the more important lessons The Lord of the Rings has to teach, as she becomes an unlikely hero to those who had consistently refused to give her a chance.

This will only make sense if you have read the books. Peter Jackson did not include the Scouring of the Shire in the film version of The Return of the King.

Bent Out of Shape: The Ring of Power and the Wraithing of Humanity.

It runs against human nature to reject an advantage once we have it, but that’s what Tolkien’s heroes do again and again. It seems natural to long to wield power and to have great authority, but Tolkien uses a Ring and a concept—wraithing—to warn us against the terrible, corrupting force of absolute power.

“And here is where I take a brief aside and beg you to please read the books if you have only seen the movies, because Peter Jackson utterly destroyed Faramir’s character in the movie.”

See Tolkien vs. Jackson: Differences Between Story and Screenplay. For myself, I had read LOTR many times before seeing the first movie. Hence when seeing the movies my mind automatically filled in the parts Jackson omitted, and corrected those he changed. The books come first, in more than one way.
