Salem Witch Trials, really? Every other worldly ability these days is suggested as the cause for the Salem Witch Trials to the point that it’s become a cliche.
The Paladin are what?
Why is Samuel L. Jackson after them so fiercely? Why does he care that these kids can jump beyond the criminal element of Hayden’s character? Because not only is the whole only God should have that power reasoning weak, he apparently doesn’t know what omnipresent actually means.

Why does David go home after Roland attacks him? Because he needs to disappear? I don’t understand how Roland’s attack drives him home when he’s been away for 8 years or something. (Yes, you could argue that he went somewhere he felt safe or thought he could hide or that was familiar but because of his backstory with his father all of those are weak.)

If David’s never met another Jumper and knows nothing of that world how does he know the terminology jump site or jump scar or think he can follow Griffin through his jump scar? (not the biggest plot hole but bothersome more because of how choppy other elements are).

So, these humans create wormholes. How do they propel themselves through, especially when they’re not moving? How did David move a stationary building through one? What are the rules for jumping – how, when, what and what are the limitations?

Variety pointed out quite nicely that the “war” that Griffin is referring to is really more of a skirmish. Or, at least that’s what we see of it. Why reference a centuries old war and show us so little of it?
