I don't know - I think the author was hoping for tremendous indulgence from Kubrick when attempting to get him to green-light quotes like:

'There are good things in Lolita. But in too many respects it squanders, impoverishes and conventionalises its source material, draining it of its complexity, nymphetry and eroticism.'

It's valid criticism, because it's a point of view, but I wouldn't expect anything quite that harsh in a collaborative work.
