Some things that didn't make sense to me... *spoilers*
1) Why would Susy go through that much trouble for a china doll that she has no sentimental attachment to? She has no idea what's hidden inside it, and all she knows is that some crazy lady unloaded it on her husband Sam at the airport. In other words, it has zero significance to her. So when the bad guys finally reveal what's really going on, why not just give the damn doll up? Why fight so hard to keep it?
2) Why didn't Susy turn out/break ALL the lights in the apartment? She left the light in the dark room on, and it ended up helping her attacker later on. Did she just plain forget about this light, or keep it lit on purpose?
3) Instead of sending Gloria to go wait for her husband, why not send the little girl straight to the police? This was the one point where I really had to overlook extreme stupidity in order to enjoy the movie.
Perhaps someone could enlighten me?
