This is a solid, well-crafted submarine thriller that 92% of critics liked for good reason—it's tense, technical, and takes its subject matter seriously.
The challenge? It's a French film (so likely subtitles), it's methodical rather than explosive, and it requires genuine attention. This isn't background viewing. If your teen loved Hunt for Red October or enjoys technical military content, this is a great pick. If they need constant action or can't handle reading subtitles, they'll tap out in 20 minutes.
The WISE score reflects that it's quality content with educational value about a specialized field, but it's not going to appeal to every teen. The 74% audience score (vs 92% critics) tells you everything—it's good, but it's not a crowd-pleaser. Perfect for the right kid, a slog for the wrong one.
