Narratively, The Fellowship of the Ring is a solid beginning to the adventure, and it’s obvious that the trilogy was originally intended to be one whole book, and I kind of still view it that way, same for the movies; the extended editions feel like a whole mini-series rather than three separate movies.
Tonally, I love how Tolkien writes. There is a seriousness and gravity to the story, but there is also great lightness and humour, especially at the beginning; I found myself chuckling aloud at the drama of Bilbo’s dealings with the Sackville-Baggins family. Another thing that felt better in the books was the passing of time. In the movies, the fellowship’s journey doesn’t seem to last anywhere near as long as it does in the book, and that’s because those epic aerial shots in the films don’t last anywhere near as long as Tolkien’s descriptions. And rightly so, different mediums have different ways of telling a story, and a film can’t dwell on the small details for as nearly as long as a book can.
However, one thing I will say against the book is that I kind of found Tom Bombadil a bit shit. There I said it. In my opinion, Jackson did well to leave him out of the movies as he doesn’t really serve much purpose to the wider story thus far anyway (does he even come back again?). I know there’s a divide between Lord of the Rings fans about Bombadil, and I must say that I am on the side that sees him as a non-entity. Maybe that’s harsh, but I also feel in further re-reads I’ll probably skip his chapters! Perhaps, it’s his selfishness that irks me, as it’s clear that Bombadil is too wrapped up in his own life to worry about what might happen if the ring gets into the wrong hands. Even stoic and eternal Elves, ancient Ents and the majestic eagles help despite their ‘oldness’, so to have Tom Bombadil sit out the most important fight for middle-earth just exposes him as an absolute arsehole. That's the tea ☕
