Jina and the STEM Sisters is a blatant act of propaganda. And its intentions are excellent. This is a musical puppet show that sets out to encourage girls of eight and older to take up careers in science where women remain under-represented. The heroine, Jina, is a schoolgirl who embarks on a hike through a dark forest haunted by ghosts and demons. It’s not clear to the viewer why she’s there or where she’s going. And she hasn’t a clue either. Perhaps the forest represents the world of intellectual repression she inhabits. ‘I ask a lot of questions,’ Jina tells us. ‘They say, “too many questions”.’ That’s an odd start.
