Maybe I jumped on the band wagon a bit with this one but after seeing the film I felt a bit guilty about never reading the book. I have now remedied the situation and here's what I think.
The book was very easy to read, maybe because it is primarily published as a children's book. I was a bit apprehensive at first as it was written in 1937 and Tolkien also has a bit of a reputation of being wordy but I was pleasantly surprised. It was a thoroughly enjoyable read without having to decipher any meanings or read between the lines. The reader is drawn into the world by the brilliant narrations of the author, not cajoled or bullied into believing that the world is reality, like some books I have read. The style is down to earth and friendly, however each character was his own voice which is distinct! Never at any time does Gandalf sound like Bilbo.
The songs in the novel add another element that is rarely found in other stories in this genre. They add a level of humour on some occasions, for example, when the dwarves are captured by the goblins and marched off to the under mountain they inhabit, they sing a song with onomatopoeic words. The scene would otherwise be full of threat. Some would think that this device detracts from the scene but I feel it adds to an otherwise dangerous scene. The song of the elves as the heroes approach Rivendell for the first time. It adds a sense of mischief and wonderment to what would be an otherwise bland scene.
The world that Tolkien writes in is perfect, there is no other word to describe it, just perfect. There is so much detail that the reader learns which makes the novel rich, however there is much that is not touched on and this is what makes the world complete. The added mystery of not knowing anything is far better than having every aspect explained. Gandalf's power is never explained, nor is where Beorn originates from and it is this that makes the world seem real.
There are many other brilliant points about this novel and I could go on and on about it however, it would be better if you went and found out for yourselves, go and read this book, its well worth it!
