I enjoyed the movie which I saw in the last class because it looked like SF movie. However, I was really surprised at the scene that four birds killed men. Those birds were very terrible.
I think natural selection expresses the bond of company especially parents. So birds saved main character. Also, there is a risk in the movie, that is to say, people proceed to wrong way. If those birds met the bad man for the first time, they would save the bad man.
