I've never read such heresy! This poet is an important part of our cultural heritage.
However, his work does seem to appeal particularly to children, men and the English. Dare I suggest, malone, that because you are a Scottish woman that is why you have never met anyone who likes it and it doesn't appeal to you?
As for its literary merits, I notice two of his poems have made it into the Oxford Book of English Verse. It is nonsense verse but it makes more sense to me than a lot of other poetry I've read. Try reading the poem that begins "You are old, father William" and then compare it to the Robert Southey original to appreciate it all the more. It's hilarious!
