Plot hole: When John arrives at Diana's crash scene, he has no reason to believe that she was involved in the accident. He doesn't know what she was driving. He would have just assumed it was someone else and kept driving through. But instead, he gets out of his car and asks where the children are, just assuming it was Diana there, for no logical reason.

Plot hole: Wells says, "We're too late to prevent the murder of number 3..." He's too brilliant a person to not think of the obvious fallacy of that: possessing a time machine inherently means that you can never be "too late" for anything. He can easily travel back in time to try to prevent any of the murders. And he believes he can change the past because he immediately starts plotting to prevent a murder that a future news story reported. This contradiction obviously serves merely to further the plot.

Plot hole: When Arnie is driving the cop car and shooting at Conner and Reese, 5 or 6 inch holes from the gunfire are shown in the door right beside Connor. If the shell penetrated the steel door (which it could easily do - and was shown to do), there's nothing inside the door or on the other side of it to stop the bullet. Connor, and probably Reese, would've been ripped to shreds.
