Christopher Orr rather nicely sums up what's wrong with this film.
Brandon Fibbs claims the Reese Witherspoon character is a convert to Islam, but I don't recall the film itself -- which I saw about a month ago -- offering any significant clues to this effect. If anything, I vaguely recall Reese's husband saying he wasn't all that religious. (Though I guess that could have just been a lie to cover up the fact that he really IS a terrorist ... if, indeed, you think the film is open to the possibility that he might really be one.)
