Very interesting scientific wise but adding the little girl ruined it for me . . . not necessary . . . and pretty much ruined the film for me. I watch movies to be entertained, not negatively affected by them. Leaving your child is a traumatic experience. I understand in Hollywood leaving your child behind is just a simple inconvenience for most entertainers but in this film this was a terrible situation that made me dislike this film. . . . Hollywood is truly out of touch with humankind . . .
