Elisha and the Shunammite Woman

Many similarities exist between the infertility, ultimate birth and near death experience of Yitzhak and the son of the Shunamite woman. Is the death of the son a criticism of the mother who failed to raise this miracle child in a worthy fashion or is it a criticism of Elisha who overstepped his limitations as a prophet? Geihazi's repeated failures in the story might attest to his flawed personality. However, perhaps his failure is meant to teach Elisha that his success as a prophet depends on a direct, non-bureaucratic contact with the common people.
