What’s in it?

Death of a character2/5
Why this rating?

The threat of death is present and characters are lost in the course of the narrative.

Graphic injury2/5

Injuries are described in a narrative sense but lack gratuitous detail or focus on viscera.

Strong language2/5
Why this rating?

Occasional mild to moderate profanity reflective of teen dialogue.

LGBTQIA characters2/5
Why this rating?

LGBTQIA characters are part of the ensemble, but the available evidence does not show that these identities or relationships are a central focus.

Romance2/5
Why this rating?

Teenage romantic tension and relationships are present but secondary to the plot.

Frightening scenes3/5
Why this rating?

Superpowered threats, pursuit and danger to vulnerable characters create recurring suspense, but this appears more like tense YA action than sustained horror.
