The problem I had was that until the last chapter, in which Greenwood sums up the book and offers some strategies, the book reads like a catalogue of insurmountable difficulties. Women have had it tough in the past. Women still do, some more than others. Now there's a proverb. But I know women who do it.
Studies are, of course, just opinion.
You never, apparently, have quite enough. This is not a deep psychological reason for killing, it's material. So, with such a radical misreading of that film, I had extreme difficulty giving credence to any of that author's other judgements. If you read this book, out of general interest or as a reference, I recommend reading Greenwood's last chapter early on, otherwise you might be campaigning for male-leash laws at worst, or at best indulging in heated arguments at the coffee machine with completely befuddled workmates.
