Source Code is a legitimately good sci-fi thriller—the kind that makes you think while keeping you on the edge of your seat. It's aged reasonably well since 2011 (no cringey tech, solid effects), and the time-loop concept remains engaging.
That said, this is not light viewing. Your kid will watch people die in a train explosion multiple times, grapple with some genuinely dark existential questions, and experience sustained anxiety throughout. It's intellectually engaging but emotionally draining.
For teens who love smart sci-fi (think Inception, Edge of Tomorrow, or even Tenet), this is a solid pick that won't rot their brain. But if your 13-year-old is sensitive to repeated death or gets stressed by tense movies, maybe wait a year or two. The Common Sense Media age 13 recommendation is spot-on—mature 13-year-olds can handle it, but it's really more comfortable territory for 14+.
