In reply to Tyler:
By John Kirk, I seem to remember. When he was 14 John marched up to me outside Humphry's Barn (eek, have I spelled Humphry properly? Probably not!) Very aggressively he opened with, "Do you know what onomatopoeia means?" (Honest!) I tried to ease out of the situation with a playful "Woof!" But, let's face it, John was never going to be a sympathetic reviewer.
And then there was Jim on 'The Mountain Spirit'. As Harold Drasdo sagely mused many years later, "He probably regrets that now."
And didn't some American have a right go at 'The White Tower'? I loved 'The White Tower'! Was it, 'buttock-clenchingly awful' or something like that? I mean - 'buttock-clenchingly awful' - that's so bad it's good. Doubtless William McGonagall would agree.
Ah the travails of the literary life!
