Recently I was reading through a discussion on Reddit in which Tolkien's writing and prose were quite heavily criticised. Prior to this I'd never seen much criticism surrounding his writing and so I was wondering what the general consensus here is.

The first time I read through The Lord of the Rings, I found myself getting bored of all the songs and the poems and the large stretches between any action, I felt that the pacing was far too slow and I found that I had to force myself to struggle through the book to get to the exciting parts that I had seen so many times in the films. Upon reading through The Lord of the Rings again recently my experience has been completely different and I've fallen in love with his long and detailed descriptions of nature, and the slower pacing.

Has anyone else experienced something similar when reading his works? Are there more valid criticisms of his prose that extend beyond a craving for the same high-octane action of the films?
