This movie started out fine, but ended with me wanting more answers. I enjoyed Sandra Bollock’s acting, but the whole birthing scenario seemed unrealistic, as did her calling the two kids, Boy and Girl...why not give them real names, didn’t want to get too attached? Where did these creatures come from and why did some people commit suicide and others didn’t? Also, the ending, while seeming to be optimistic, seemed false, somehow. Maybe the book was better.
