What? HP 1,3 + 4 are totally rad (in a 'I read this when I was 10 and loved it') - everything else is fucking awful.
Susannah Clarke's length, though can be intimidating - I lent it to one of the kids at school though.
Epic rant, CD, epic.
I'd challenge you on the uncommon nature of a slavish, herd foaming at the mouth over something both dull and unoriginal - seems cyclic in an art form where marketing triumphs over substance (and seems to have since, basically, Victorian times).
People are idiots, but I enjoyed reading the earlier books - even if they were complete rehashings of someone else's ideas. For a 9, 10, 12 year old the originality isn't really that relevant. It probably has a lot to do with age - I can't imagine an emotionally mature person enjoying reading about a self-centred fail whale like HP.
Surely one must feel similarly about other massively popular shit: Eat, Pray, Love, or most vampire books (which are just rehashing 'the vampyr' a poem by Maxwell), etc, etc, etc.
I have a DB rant - but more about how idiotic people were in their reactions tot he novel 'Da Vinci Code' which states 'THIS IS FICTION' yet still people assume it's a re-telling of history based on research, etc.
It's all a bit silly, really.
