I bought it. Only about halfway through it. Nissen peppers his writing with one-liners and cruel jabs --not many escape them-- perhaps in hopes that we won't fall asleep at the more technical aspects of the book. Most of what he covers (so far) of Agnes' personal life is rehash but it has his own negative spin. As for Paul Gregory…..I think the point has now passed where his contributions have begun to reflect less on Agnes and more on his own character.
The only positive I can think of is that perhaps to have Agnes' filmography outlined might come in handy.
