Damien Chazelle’s First Man is a biographical drama that follows Neil Armstrong in the decade leading up to the Apollo 11 mission to land a man on the moon (1969), but while it’s strong on mission, and technically dazzling, it’s weak on biography. Who was Armstrong the person? What made him hell-bent on such peril? Did he fear never returning? As portrayed here, he’s essentially yet another strong, detached, emotionally unavailable man of few words, so this is a set-piece action film at heart.
