That whole segment pissed me off. Who gives a fuck what Art Howe thinks about anything? If he is feels like he was portrayed innacurately in Moneyball, that's his problem. He had no business rebutting the movie script point by nitpicky point on an Astros pre-game show. Of course, he had Patty Smith sitting right there, egging him on. She probably thought she had some kind of big story on her hands.
The whole thing was desultory, just like this whole fucking season. Howe may have had a legitimate complaint, but he ended up coming off as a small-minded whiner and a monumental bore.
In principle, I can appreciate what you are saying. However, our pop-centric culture has regressed into one where character assassination is celebrated and considered a demonstration of superiority. It doesn't matter the medium, be it TV, movies, news (so-called), or books. Moneyball, the book, didn't portray Howe in a positive light. But it was made clear that it was Beane's opinion. I have not seen the movie, and probably won't (although not out of any disdain for Pitt or the content), but if half of what was stated by Howe accurately depicts the content of the movie, it's simply bad form.
These are real people (Howe), who are knowledgeable professionals in their chosen field. The people making these movies should try to do/be the same. It's a simple matter of integrity.
