I remember borrroiwng the first half-dozen albums from a friend at college and being utterly unable to see anything apealing in their music at all!
Apart from Go Now - which is not their song, and Knights In White Satin, which is one of my all-time favourite records, the appeal of the Moody Blues joins that of bands like Coldplay, Blur, Elbow, Jethro Tull, and so on, in being an alien concept to my ears.
