Visible crew/equipment: When John and Derek arrive at the school, a crew member is visible in the car's right wing mirror. (00:06:00)
Continuity mistake: When John and Pyle are at the shooting range, John's protective glasses are up on his head when he fixes Pyle's gun, down on his face when he fires the gun, back up on his head after firing and then back down on his face when he gives the gun back to Pyle. They're then back on his head before taking them off before the scene ends. (00:13:45)
Visible crew/equipment: After Derek speaks with General Hobbs and meets John outside, the reflection of a crew member can be seen in the car's front grill. (00:19:15)
Continuity mistake: Season 2, Episode 5: "Goodbye To All That" - We see Marty Bedell playing on his Xbox 360 with a headset attached to his right ear. But when the T-888 arrives at his house to kill him and he goes to answer the door, the headset is gone. There was absolutely no time for Marty to remove the headset as the camera cuts too quickly.
Continuity mistake: At the range when the boy's gun jams, you can see tape on the bottom of the magazine. However, when John goes to clear the gun, the tape is missing.
Continuity mistake: On the firing range when John Connor fixes the stoppage on the rifle, his shooting glasses are on his head, when he hands the rifle back, the glasses are now over his eyes, and in the next shot they are on his head again. Not enough time has occurred between shots for this to happen.
Other mistake: When Sarah puts Marty on the bus on his way home he steps onto the first step and turns to face Sarah as the door closes and the bus departs. It is against the law in California for buses to begin moving until passengers are on the main deck of the bus (one step up from the boy). This law was enacted after a child fell from the entry step of the bus (exactly where Marty stood), the doors opened and they were run over by the bus. California operates a zero tolerance policy on this matter; drivers know that a single infraction will result in the loss of their commercial drivers license and is taken very seriously by all drivers, without a single infraction having been reported in years.
Answer: It was cancelled due to declining ratings. Season Two had about half as many viewers as Season One.
