Factual error: Dr. Fielding is dead inside the JPL building. His blood is dripping onto a telegraph key and it is sending perfectly comprehensive Morse Code. The blood drips are too random to do that. (01:13:25)
Suggested correction: It's clear he was alive at one point, and the way he has positioned shows he was probably already sending that. There was a break from him sending it, and it's clear the kids didn't understand the morse code, which could be the point his blood was dripping.
That could be. OK.
Plot hole: The girl in the basement of the JPL building comes across a locked door with a combination lock. She hits a few buttons and the door opens. There was no way she could know the combination. She is at JPL for the first time in her life and everybody - except her three friends she came with - is dead. (01:23:20)
Other mistake: The girl turns on all generators in the basement of the JPL building. Yet there is no power to the basement where she is. Just flashes of light, highlighting the suspense. There is power everywhere else. (01:23:10)
Suggested correction: The building is severely damaged. There could be several reasons why the power in the basement isn't working.
You have a point. Thanks.
