Other mistake: It isn't known if Rory was diagnosed with ASD, but some of his behaviors and the two classmates in school making a reference to his "Asperger's" indicate or suggest this is the case. While Rory may have been "faking" some mannerisms in hope that the two bullies would leave him alone, his (hyper) sensitivity to noise (sound) was displayed after school when a dog was barking at Rory. However, Rory did not put his hands over his ears in the ball field despite the loud gunshots close to his ears. (00:51:54)
Plot hole: Quinn gave the box containing the Predator's equipment to a Mexican and told him to send it to a P.O. Box in the U.S. He also gave the man an unknown amount of money for the postage. Without questioning IF the Mexican would follow his instructions and had enough money, sending a package internationally is not that simple. The package would need to go through customs and several documents would need to be completed. The contents must be disclosed. It is doubtful it would pass Customs.
Other mistake: At the baseball field after Quinn (Rory's dad) slid through the green slime, he only had green slime under his neck on the front of his shirt - none on his pants or back of shirt where expected. (00:52:52 - 00:53:37)
Revealing mistake: The covering of snow was not real snow. When the trick-or-treaters are first seen, there are images of footprints (shoeprints) in the snow, but the trick-or-treaters walking over the "snow" do not leave any footprints. (00:44:38)
Continuity mistake: What top Dr. Casey Brackett is wearing (or not) in the decontamination chamber changes. Initially, she removes an off-white short-sleeved T-shirt-like top before putting on the protective gown. When she returns to the chamber, an automated voice says to "remove outer garment", which she does - but she is now wearing a sleeveless off-white top that was not under the gown. When she ducks down to hide from the Predator, she does not have ANY top on. (There may two+ different short-sleeved tops). (00:22:33 - 00:31:28)
Answer: He actually states that he sent it to a P.O. box because he didn't want it at his wife's house and potentially endanger her. But since he hadn't been paying his P.O. box fees, the postman brought the box along with some other mail to the house.
