I agree -- for what it's worth, she's been writing a series of columns about losing weight (she was 100 pounds overweight, and has lost 30 pounds so far.) I admire her for sharing that struggle with her readers, knowing that she'll be subject to ridicule for it.
That being said, I think her review of The Passion was the most over-the-top and unfair of any of the reviews I've read about the movie. And her response to some valid criticisms of her review was just plain condescending. I don't need a degree in film criticism to know that it's hypocritical for her to decry The Passion for its violence, while writing a book praising Quentin Tarantino.
