Is This Star Student A Saint Or A Sociopath?: 'Luce'

We meet soon-to-be-class-valedictorian Luce (Kelvin Harrison Jr.) as he's addressing a high school assembly in Northern Virginia, saying all the right things about a rosy future. He is clearly practiced and comfortable in the spotlight, popular with students and with So Luce's adoptive mom (Naomi Watts) is blind-sided when one of his teachers (Octavia Spencer) calls her in for a conference about a paper he's written. The assignment was to write in the voice of a historical figure — and Luce chose Frantz Fanon, a Pan-Africanist revolutionary who argued that violence is a necessary, cleansing force needed to free colonized people from their rulers. Watt's character, knowing her son as a gentle soul, reads the paper and sees that he has followed the assignment. Spencer's character sees Luce through a different lens than his parents do, a teacher's lens ... affirmative, yes, but she's worried about that paper, and she's even more worried about something she finds in his locker — which I won't spoil here.
