Query: A warning for fantasy lovers

If you loved Once and Future King especially for the humor and whimsy of Sword in the Stone, you need to know that Book of Merlyn is a very different beast. The T.H. White who wrote this revisiting of the Arthur matter is not at all interested in story. He even seems to be using Merlyn merely as an excuse; what he wants is to vent on some pet philosophical ideas. And White had become seriously embittered and misanthropic by that time. The book was very disappointing to me and left a bad taste in my mouth. I choose to consider it NOT a valid part of the Once and Future King canon.
