I think it could have been done better, and made the Martyr theme more prominent. Instead it was "watch a woman who is traumatised, go through more trauma and body horror".
Actual martyrs died for a cause or a religious reason. She didn't have a long held personal belief that would warrant such treatment, it was just a fucked up cult doing it to her for a stupid reason.
I'm glad that dumb cult didn't get the answers they wanted.
