Phixius

Corrected entry: As they main characters walk to the ferry, there is a blood donation lady explaining that they are full for certain types of blood. Why are they taking blood donations? The aliens vaporise every part of the human body. The only reason they would need blood is if limbs were torn off (And people shooting people would not be the cause to ask the Red Cross to call for a national blood drive during an alien attack).

Corrected entry: When Tom Cruise exits his ex-wife's house where the plane has crashed, you see one of the rotors turning slowly. The plane crashed late the night before, that rotor would surely have stopped turning by now. It didn't look like it was that windy outside and even if it was; it would take a big gust of wind to keep it turning.

Corrected entry: As the three drive away from the bathroom stop, after encountering the Army for the first time, we can hear the sound of the EAS (emergency alert system) on the radio, then the announcer stating "This was only a test if this had been an actual emergency." If ever there was a time for the EAS to be activated for real, this would be it.
