Factual error: The coastal wall in Sydney is shown as being inside the Sydney Harbour (right next to the Opera House). But Sydney Harbour is not on the Pacific coast but a part of the Parramatta river, several kilometres from the ocean (where the wall should have been). So the wall is either not shielding the northern part of Australia or (more likely) the producers decided that the audience cannot tell that it is Sydney unless we see the Opera House.
Plot hole: The Kaiju's EMP fries all electrical circuits next to him, and affects the base as well. If that's true, how did the helicopters carrying Gypsy survive the blast without having their electronics fried? EMP pulses induce current in all electronics regardless of whether they're powered on or not. (01:18:00)Marcus CaptainSlow Belicchi
Question: What I don't get about this movie is when ever they fight one of these giant monsters, why do they always engage in hand to hand combat for most of the fight? Its not until the end of most of the battles that they remember they have weapons to fire at these beasts and kill them which works with the category 1-3 beasts just fine. Why not just shoot the things?Carl Missouri
Question: Is it ever established why the Kaiju attack cities? Why they perceive a challenge, a threat, a resource worth taking there specifically? If they are a decent biochemical match to Earth life, and are hungry, why don't they attack schools of fish, or fishing/whaling vessels, if nothing else, they should attack the cannery row? If they are after a non-living resource, like minerals, why don't they root through the seabed or attack mines?dizzyd
