Touches of topical humor, such as Quinn acting out the Star Wars story for community children, mix with moments of religious allegory as the children recite lessons in dragon survival like a memorized prayer. Alex refers to the skydiving team that tries to net flying dragons, as Archangels. And numerous crude expletives along with some strong profanity, mostly used by Van Zan, color the dialogue. But, while a fist fight gets briefly brutal, most of the violence is limited to killing the flame-spewing dragons. However, several tense scenes may upset children under ten and strong profanity drags down the REIGN OF FIRE.
