Excellent movie.
Overall a great movie! However there are a few things which I think should be mentioned. When the camera is facing her as she is running, it [her run] appears awkward and unnatural, unlike with the other camera angles which are superb.
Also the story is thus far AWOL. We don't know why Los Angeles appears to be a ghost town, why this woman is driving into LA, nor why people are shooting at her. I suppose this is because the movie is merely a teaser - but there still should be some story line.
