French Canadian wunderkind Xavier Dolan (he made and starred in I Killed My Mother at 19) seriously gets in you face with the extravagantly jarring Mommy. The brutal arguments between out-of-his-mind, tantalizing, violent-zero me, ADHD 15-year-old Steve (Antoine-Olivier Platt) and his tough yet unconditionally compassionate mom Diane (a great Anne Dorval) have to be seen to be believed. Dolan has an eye for marvelous shots and his use of the narrow 1:1 screen ratio, highly effective In itself, produced an anticipation of wondering when he was going to spring the change of ratio to full-blown wide screen. Technical marvels aside, Mommy is essentially about a mother’s love. After Steve, who’s also been known to wet his pants, expresses fear to Diane that she’ll stop loving him, she replies, “What’s gonna happen is I’m gonna be loving you more and more, and you’ll be loving me less and less. That’s just the natural way of life.”
