Over-promise and under-deliver. The premise was interesting but it failed to develop it into an interesting story. Certainly, the sci-fi setting of growing a baby outside the mother’s womb was fascinating. I get dissatisfied with a film when a character personality or behavior changes dramatically without any plausible reason, this happened in this movie. There was an inkling of interesting character development when Rachel started feeling guilty and doubtful about her maternal instincts. I wished this had been explored more. I also wished some entities and characters who were diametrically opposed to the main characters were more realistic and complex.
