I've always had mixed feelings about CT's approach to his father's work. For whatever reasons he tried to relegate the works to the realm of academe. I'm grateful he made the unpublished works available, but the accompanying mass of notes and commentary he added makes them (apart from the Sil) an horrific chore. He clearly hated the fact that his father's creation he been taken up by a bunch of hippies (many of them lefties too
), and sought to return them to their 'rightful' place, by handing them over to a bunch of professors. Most of the stuff he published would have been better if it had been put out with a basic 20 pp intro. The LotR movies (critical as I am of many parts of them) contain more of what touched the hearts of most book fans, than the interminable droning commentaries of CT, Flieger, and Hammond & Scull, et al
