Continuity mistake: When Quigly is launched into the pool. He is quite obviously going at an angle, but when the shot cuts, he falls completely straight down into the pool.

Revealing mistake: When Preston crashes into Quigly in the bowling ball to send him into the pool, you can both see and hear the launchpad that actually launches him.

Other mistake: When Preston puts the VR headset on Beiderman, he reacts in a very strange manner. Yes, it's better for the movie, but it doesn't make sense in-universe, as it would take very little effort to simply lift the headset off to remove it.

Other mistake: During the park chase, Preston swipes the backpack from the person that picks it up, and is still being chased by Quigly. He somehow manages to put the backpack on in a span of about 7 seconds. Considering he is pedaling for his life, and the fear of the men catching him, it's unreasonable to assume that he could have done such a feat so quickly.

Continuity mistake: During the park chase, Preston loses the backpack in a wooded area, but it inexplicably winds up in an open area a few minutes later.

Character mistake: Quigly says that Preston "got away again" when he and Shae escape in the limo, but that was the first time that the trio found him after he got the money.

Other mistake: When Preston's dad starts to back out of the driveway, he abruptly stops to avoid hitting the moving truck, as if it had just recently appeared there. But they've been there for a while. As soon as he stops, he gets out of the car to start complaining, and the truck driver has already been out of the car for a significant amount of time.

Plot hole: To buy the house, Preston would have had to sign some papers in-person, and no realtor would let a young child act as an intermediary (for "Mr. Macintosh") for such a legal procedure.
