One difference between the Lord of the Rings books and the Peter Jackson films that I find really interesting is what the hobbits find when they return to the Shire.
In the books, they return from the War, only to see that the war has not left their home untouched. Not only has it not left their home unscathed, battle and conflict is still actively ravaging the Shire. They return, weary and battle-scarred, to find a home actively wounded and in need of rescue and healing. All four launch themselves into defending their home and rousting those harming it, and eventually succeed. But their idyllic home has been damaged, and even once healed, is never quite again the Shire they set out to save.
In contrast, in the Jackson films, they return to a Shire shockingly untouched by the horrors of war. The hobbits of the Shire talk, in the Green Dragon in Fellowship of the Ring, about not getting involved with issues “beyond our borders,” and it seems those issues have not invaded their sanctuary. After having been bowed to by kings, dwarves, elves, and men alike at the coronation in Gondor, their only acknowledgment upon returning home is a skeptical head shake from an older hobbit.
One of the most poignant scenes to me in Return of the King (and there are a considerable amount) is the scene where Frodo, Sam, Merry, and Pippin are sitting in the Green Dragon. The pub patrons bustle around them, talking loudly, clapping excitedly, drinking cheerfully, just as they had in the beginning of the story. But the four hobbits sit silently, watching almost curiously at what was once familiar but is now foreign to them. Their home has not changed. But they have.
Which is the deeper hurt? To come to your home to find it irrevocably changed, despite all you did to keep it untouched and the same? Or to return home but no longer feeling at home, because it is only you that is irrevocably changed?
In a way you could probably use the War analogy for two countries, UK and US. It was nowhere near to the extent of WW2 but Britain was bombed during WW1 so the country Tolkien returned to was damaged by the war. Meanwhile the American soldiers who returned to the States found themselves in a place unchanged by the war, but they themselves were changed.
