There is always one damn person that can't follow the rules, and causes the world to end. If the son would have just stayed inside the house every thing would have worked out.
shareIt probably still would have happened. He just sped things up.
The spider spinning his web for the unwary fly. The blood is the life, Mr. Renfield.
Well things looked like they were being taken care of.
shareDid you cuss at the kid in 28 Weeks Later? We sure did here! The one stupid brat re-infected all of London/England, caused thousands of deaths, and then went on to infect Paris/France/the rest of the world, too. That Anthony Michael Hall/Daryl Hannah movie a couple of years back, Zombie Night, was the same. One idiot brat has to run and unlock the door his zombie sister is locked behind for God only knows what reason and in effect gets his entire family killed and a half a dozen others, too. Always one in every movie.
shareWell, if you had noticed, by the time he opened those trucks, almost their entire neighborhood was empty. When the military took off running, there's a reason there was only that handful of people that got out of their houses finally and were wandering around. Because the military had already rounded most of the neighborhood up, and executed them. So that was likely the fate of the remaining folks, including his family. They were more than likely going to be killed.
So in that sense, it didn't matter that he opened the trucks. But on the other hand, it makes no sense that Sonja's mother would be attacked, bitten by the father, and the military people would NOT see that, and execute the mother too. Probably Sonja as well. Hell, they had no problem murdering an entire family in that minivan that was trying to escape.
Ultimately, the crappy ending showed that in spite of appearances, the government obviously didn't have everything under control, so while what he did didn't help, the only people that it actually hurt, was his family and the remaining survivors.
