Why Watch This

This case sits at a genuine, still-unresolved intersection of psychiatry and criminal justice, and the series doesn't pretend to settle a debate that split expert opinion at the time and continues to divide people today.

If Monsters Inside's psychiatric-defense angle interested you, The Devil on Trial covers another case where an unconventional defense strategy became the central controversy.
