Boys should want to act heroically at certain points in their lives. Being independent and self-reliant, getting up after having been knocked down—these are absolutely critical skills. But because these characters never show sadness, fear, anxiety, or obvious enthusiasm and love, they constantly teach and reinforce that boys should limit their emotions, and they even tell boys which ones they’re allowed to have. They don’t show how a man should speak out in a morally complex situation when his loyalties are torn between friends and ethics.
