Headscratchers / Colossal

• How did Gloria know that she and the Kaiju could switch places if she went to Seoul?
  • She probably didn't fully, only operating out of desperation and a wild guess due to how their bond works.
• Did anyone else notice the kaiju appearing in New Hampshire? Was there any additional damage caused?
  • There were children heading to school just minutes before. Gloria's neighbors were probably awake and aware.
  • The kaiju's hoofsteps shook the ground, enough to make a person lose their balance, from a huge distance. Since the first sign of any shaking was enough to make Oscar stumble, the kaiju's steps were strong enough to cause such an earthquake the moment she appeared in the suburb, even from the other side of the zone where it could exist.
  • Surely someone would notice the eviscerated playground and the massive hoofprints leading up to it from the forest.
  • Somewhere past the trees that overlook the playground is a forest trail, which the kaiju may have encountered. Given the sheer scale of the kaiju compared to a human, though, she may have had to trample a neighborhood or two to reach the playground.
• How could Gloria in Seoul know the exact position of Oscar in the US, to the point of being able to pick him up with her kaiju avatar, instead of just having the monster blindly stomp the ground? It's made clear (and Garth even realizes it) that her movements control the monster directly but she has no awareness of the monster's surroundings. The same goes for Oscar apparently trying to stomp a kid in Seoul with his robot, despite not really being able to see him.
  • The Oscar and the kid thing can be chalked up to coincidence; he didn't actually know exactly what was underneath his foot, he just had a general idea he'd be stomping on a populated area. Gloria's actions, though? Probably just the movie disregarding it's own rules and internal logic for the sake of a cool moment. If you have to justify it, though, perhaps both are because the longer they interact with the phenomenon, the stronger their connection to it grows, allowing them better (perhaps subconcious) awareness of their avatar's surroundings.
• It has been several days since two giant beings continued to appear in a certain zone of Seoul at a fixed time of the day. Surely the people would have learned to avoid that zone, and the military would have cordoned it off from the rest of the city? But in the finale not only there's hundreds of people around, with shops and locales being very much active, Gloria even walks right where the giant robot appeared, with no soldiers or anyone even trying to stop her.
• When Oscar sees the kaiju coming for him in the US, he walks back and gets past the bounds of the playground, yet his robot avatar in Seoul does not disappear. The robot does not disappear even when Gloria's kaiju picks Oscar up and flings him in the distance.
• Why were the attack helicopters shooting Gloria the only time the military apparently tried to fight the Kaiju? Sure, the damage the missiles actually did the Gloria was minimal, but from the army's POV, it would look like they shot the Kaiju several times, it flinched every time, then fell down (and perhaps the robot picked it up and carried it away until they both disappeared), so it would look like their weapons were rather effective. They should have had whole fighter squadrons on standby every morning, if not bigger weapons (potential civilian casualties their only limit.)
