If you're interested in learning more about the film, I can suggest some possible resources:

Most erotic films fail because they remove the shame . They present sex as friction without consequence. Tarzan X wallows in shame. Jane covers her body, then uncovers it. She prays to a God who clearly isn’t listening. She tries to build a raft to leave, then sabotages it herself. This is not bad writing; this is psychological realism for someone trapped between two worlds.
