Corrected entry: The sphere says that the attacking aliens' ship will leave if the alien queen is killed, even though moments before the sphere said that no one has ever defeated a queen. (01:00:00)
Corrected entry: When the new president talks to the world on shortwave radio, some kids are adjusting a TV antenna in one shot. Shortwave radios wouldn't work with TV antennas, they use two significantly different frequencies. Shortwave is a much longer wavelength and would require larger antennas to work.
Correction: As any shortwave listener will tell you, quality receivers will work with just about any length of antenna. I have $10 receivers which work just fine with the 24 inch built in antenna.
Correction: They are using alien technology to improve everything they use. Therefore, I'm sure that technology is enough in this situation.
Corrected entry: It was quoted in the film a number of times that the "Harvester Ship" was 3000 miles in diameter, ("It's over the Atlantic." "Which part?" "All of it.") yet there was apparently no problem flying to the centre of the ship in 3 minutes, and back.
Correction: Humans have incorporated the alien technology over a period of 20 years, creating much more advanced means of transportation such as jets that could fly into space. In the last movie, it took the giant destroyers less than half an hour to detach from the mother ship to their target cities.
Corrected entry: When David and Catherine are heading to the alien city destroyer in Umbutu, which used to be part of the Congo, they are surrounded by desert landscape similar to the southwestern US. No such landscape exits anywhere in the Congo. The country is covered in rainforests and grasslands. You can even see the Sandia Mountains which are in New Mexico in some shots.
Correction: They are in the fictional National Republic of Umbutu, as its borders are never defined it's entirely possible that the fictional Nation could have such desert landscapes. It's also possible that the presence of the landed City Destroyer coupled with the fact that it was trying to drill to Earth's core could have altered the ecosystem in the area.
Corrected entry: In the scene where Singapore is destroyed, the Fullerton Hotel is beside the Museum which was beside the Marina Bay Sands. In actuality, they are far from each other, and there is no Singapore Ferris wheel or Singapore Flyer.
Correction: This is a fictitious world where many cities were destroyed by an alien invasion and then rebuilt so we can forgive these differences.
Corrected entry: In this film the aliens are said to be operating with a hive mind, and are all telepathically linked to the alien queen on the mothership. It is also stated the mothership from the first film also had a queen that was never seen. If that is the case, then there would not have been any need in the first film to use Earth's satellites to coordinate the attack.
Correction: There could be a distance factor involved. The mothership in the first film stayed outside of Earth's atmosphere. The Harvester ship in this film landed on Earth with the queen on board. In the first film the city destroyers entered Earth's atmosphere at areas around the world. So it could be that they needed to use the satellites in the first film to coordinate with the Destroyers inside Earth's atmosphere which were spread all around the world. Also, in this film The Queen goes to Area 51 on board her personal ship and she controls the fighters which are very close to her as she exits her ship therefore not needing any satellites.
The aliens didn't need the satellites to control their ships, they only needed them to send a countdown timer to one another (which is ludicrous all on its own). They are linked telepathically to one another in addition to the queen, former President Whitmore, Dr. Okun, and Umbutu. These people are all spread all over the planet and still have a link to the aliens. Also, the captured aliens rejoice in unison when they realise the queen is coming yet they are nowhere near her and have no means of knowing this other than their psychic link.
Corrected entry: Lt. Whitmore fires 2 rounds at an alien fighter before her weapon locks back in the empty position. In her next shot the weapon is in the fire position. (01:47:20)
Correction: There was plenty of time for her to release the slide forwards.
Correction: The sphere is the most intelligent entity in the galaxy and therefore is comfortable with predicting that killing the queen will produce the result that it ultimately did.
