Well, I've finished it - but I'm afraid there was no magic in the reading for me. I suspect this is something a younger reader might find - and return to with later readings - especially if they don't know too much of the story.
For my part, all too often the only sections that felt new were those cut from the films as unnecessary, and so never really satisfied.
Some further observations:
1. The section with Faramir meeting Frodo dragged - it seemed more like a 32-page recounting of the story to date, than an actual story development itself.
2. Imrahil - the most underrated character ever! He personally saves Faramir against a Ringwraith, he later does the same for Eowyn, and is not only given control of the army at the Battle of Pelennor Fields, but also of Gondor during that time! I'm surprised I've found so little information or discussion about him, as he seemed a pivotal character.
3. The Rohirrim hunt and kill men in the hills, and murder anyone looking at their sacred pools in the wilderness - yet these are the good guys?!
4. I'm really surprised Denethor didn't reveal Frodo's mission when using the Palantir. Before this, we were told Saruman used one to communicate with Sauron, and yet Denethor simply seemed to get automated images to his questions. It felt like inconsistent handwavium.
5. The Orcs killing each other over Frodo's mithril shirt seemed both convenient, and somehow Tarantino.
6. The Scouring of the Shire felt very out of place - somehow childish by comparison of what came before, yet also morally debatable: rounding up ruffians and then killing them?!
7. Before reading it, I might have suggested that LOTR was a book about language, but really that seemed to play only a minor part in the prose. Instead, it was more about walking places, describing - then naming them. Arguably it's as much a narrative about a map with further information provided.
