What does the title mean?

Anyone know what it means?

Also ... Premise was good. Acting was good. Plot was not.

I thought this was going to be a little different, somehow incorporating more of the terrorist subplot. The story would've been fine without. Probably better since it really has nothing to do with terrorism. There's another "lesson" here; maybe not lesson, but a message.

Also not exactly sure what they tried to do with the ending. I suppose just to add some of the "outside world" elements, since it's during terroristic times. And it obviously doesn't matter; director/writer also knew that since they just left it open that way. Again, if it doesn't really add to the plot, why put it there.
