Formulaic but fine for a single watch

Premise: A woman is stalked and kidnapped by a random stranger intent on... something. Raping her? Cannabalizing her? Torturing her? Although the stalker's ultimate intentions are never clear, this otherwise sticks to the genre rules, i.e.

i. The stranger keeps coming across her on all these back roads of Oregon, despite the fact she deliberately takes different routes to avoid encountering him again and again. How is he finding her? How does he know that she won't turn off somewhere else when he is ahead of her?

ii. Cell phones are lost or damaged at inopportune times. Or reception is sketchy.

iii. 911 operators insist on asking for details before responding promptly to a curt call for distress.

iv. In a surprise move, the woman DOES NOT randomly trip and twist an ankle while fleeing her captor in the forest. Oh wait!... there it is. She jams a twig inches deep into her bare foot with the same result, i.e. she is forced to limp along.

v. The woman insists on running at night in a dark forest, thus ensuring the noise she makes, the mist of her breath, etc. gives the predator the means to track her. Why doesn't she just hunker down in the underbrush until he passes on? In fact, she does this very thing later in the movie anyway.

vi. Boneheaded decisions by the woman, e.g. she sneaks into the villain's car, grabs his cell phone... and then decides to make the call right there giving him time to return and find her.

vii. The villain is able to absorb huge amounts of punishment and and not pass out or die from extensive pain and/or damage. Here he takes four or five blows in a row to his skull and arms with a tire iron to no lasting effect.

vii. When she comes across a stranger who might help her, rather than giving him a clear, concise description of the situation, she babbles and screams in bursts, thus ensuring the stranger is confused and buying time for the villain to find them and re-capture her.

The only thing that somewhat redeems this is the passable acting.
