The good stuff
Although the movie makes it clear that Joseph Wilson is trying to do the right thing by telling the truth about the war in Iraq, instead of accomplishing something positive, he and his family lose their peace of mind and their well being. The United States government (circa 2002-2003) is portrayed as a formidable villain, and the characters are tempted to give up, but they keep fighting. Their victory is small compared to the price they've paid, but they at least meet the challenge.
Both Joseph Wilson and Valerie Plame could be considered positive role models in their own ways. Wilson is shocked to hear that the government has lied to the American people and tries to help spread the truth, even at the cost of his wife's job and their family's well being. Plame is personally involved with one of her projects, trying to save the lives of a family in Iraq before the war starts. She's tempted to give up the fight, and her marriage suffers great tension, but both she and Wilson persevere against all odds.
What to watch out for
Several tense arguments and shouting matches, and characters receive death threats. The entire story takes place on the verge of war, which adds an underlying tension to the film. Subsequently, viewers see a few attacks and explosions in the Middle East involving secondary characters.
