@ 12m50sec Spencer corrects his daughter Zoe that the "plague" took place in the 1400's, when in fact the Black Death took place in the 1300's. (Plague or Bubonic Plague is an acute infectious disease caused by the bacillus Yersinia Pestis .And while Spencer most likely meant the black plague there has been 3 other outbreaks apart from it -The Justinian Plague was in 541( starting in Ethiopia spreading to Western Mediterranean) , Great Plague of London 1665, then there was the 3rd Pandemic of 1894 which spread from China to India to Australia in 1900 and other places mostly finishing 1957 but is actually still around today in pockets.)

about 40min the radio gives the asteroids impact incorrectly as latitude as 42.495821 , -75.076065 . Because it omits N or S for the latitude and E or W nomination for the longitude to make it valid. There is no such thing as negative longitude. You cant find it on a map. As there's 2 40s and 2 174s , without nominations you have 4 possible combinations of location if you were to guess. For e.g. Oneonta correct latitude , longitude is 42.4529° N, 75.0638° W.

It's off that Spencer doesn't react or reply to Kemmy stating that his father had died recently.

They are told they cannot get any internet including satellite while they are able to speak fully on a smart phone just outside their bedroom window. This means they can indeed set up antennas or satellites for hot spots for the internet.

The news reporter that arrives on Spencer's property asks if Spencer is "Stewart Coleman", to which Spencer does not correct him.
