Ok, I shat a few bricks thinking about this the other night and tell me if I'm wrong but...
*SPOILER*
The beginning of the movie starts out with Rob screwing around with the camera and Beth and stuff, yadda yadda.. Later that night at the party, Rob asks the cameraguy if he was using a new tape or was overwriting the tape that was already in there. He is clearly disappointed with the answer being the latter. As the movie progresses, there are certain parts where the movie cuts back into footage that was being overwritten. Examples include when they rewind the tape to see the monster after the statue of liberty got own'd, there's the scene where Rob and Beth are on the train. Anyways, the whole movie was an intense ride culminated with a taste of irony at the end with the last footage shows them having a great time with each other about a month before they supposedly die. Great movie, story well played out EXCEPT FOR ONE THING. If I know what I'm talking about here, this could be a major plot hole. Now again, tell me if I'm wrong.
In the very beginning of the movie, didn't it say that all this footage was recovered from "an area formerly known as Central Park?" Yes it did.
I think they also mentioned that the camera recorded it all on a digital SD Card.
I'm curious to know if anyone else has noticed this.
