It was Silky, Moonface and the bloody Saucepan Man that I loathed, even as a child who adored virtually all other Enid Blyton — the basic scenario of a magic tree whose topmost branches are visited by different magic countries is a good one, but the characters are either completely generic (you could switch the names of Jo, Bessie and Fanny around without changing the story in the slightest, other than Jo bossily thinking he has to ‘protect’ the girls) or the generic wrong’un child who gets reformed (Connie, Dick) or idiotic/ cantankerous (Angry Pixie (angry), Saucepan Man (comedy-deaf and stupid), Whatsisname (sleeps).
I always felt I should like it more than I did, as EB is clearly trying to convey that the children’s family is actually poor (they have to walk the five miles from the station, the mother wants to take in washing, the children do all the housework and grow food in the garden), rather than the UMC world of the Famous Five or Five-Find Outers, with their cooks and maids and deferential farmers’ wives and WC Ern being sent to have tea in the kitchen, but I think it’s a weirdly violent fictional universe. The kids get slapped at home for not doing their jobs properly, and there’s also a lot of punishment, smacking, scolding etc in the fantasy parts.
I think the recent reissues changed the children’s names and took out all the slaps.
