Extraordinarily Stupid
1 - Why did the boyfriend had to smash his car and get killed to buy her time. He could simply have laid down in front of the taxi seeking help etc.
2- Why did she have to turn out all the lights. What an idiot. In the end, she got undone by her own foolishness as she could not search for christopher
3- Why o why do you have to go through such an elaborate scheme to steal baby i.e. kidnap babysitter, forge identities etc. Just go to a less populated area and steal a baby in the park by pushing the mother aside. Simple as that!
