I saw it last night on television. From what I saw, it seemed to focus on the police and firefighters who responded to the horror. It seemed pretty heartfelt really.
The very end of it made me think it would focus on Nicholas Cage (who looked really skinny in the face to me) and the other cop while they are trapped. It certainly appears that there won't be any "America is responsible for what happened" editorializing in it. But still a little early to tell.
