I disagree. I'm a woman and I didn't fancy it because of the (apparent) subject matter, but my sister, whose judgment I trust, recommended it, so I watched it last time it was on TV (and again this time). While I didn't enjoy the bloodthirstiness, I recognize that it was necessary, and I enjoyed the film, because there was a lot more to it than just a straightforward gorefest.
My favourite Brad Pitt film, by a mile, is A River Runs Through It - a beautifully made, very moving film. BP has never looked so good, nor been so good, in any other film, in my view, partly because the role fitted him like a glove, and partly because Robert Redford, as director, truly understood him and his appeal.
