From the Wikipedia article it seems to work rather well:

An early U.S. government sponsored study found that batterers who complete programs based on the Duluth Model are less likely to repeat acts of domestic violence than those who do not complete any batterers' intervention program

And the feminist author seems to have realized it short comings herself. But sure like with anything there will be bad expressions of feminism.

I really don't get why you prescribe the violent aggressive man to feminist theory. It's the opposite - that is the classical view of men and often the root of the problems men face in society. Feminism on the other hand tells men that they can have other roles, they don't need to be the defender, protector, earner etc. - does not mean that they can't - but that they can chose. It's the conservative view that puts all the pressure on that you are experiencing.
