The plot is good, the set up for the story is good, but there are way too many improbabilities in this story.
How could the Killer (character Ben Zelko, played by actor Luke Askew) have known that Cannon was going fishing in that place on that weekend?
And the cute puppy scene. Would someone really run back to a cabin to retrieve their dog, knowing that a psychopath was there waiting to kill them?
And how about Cannon getting run off the road, down the side of a hill; the Lincoln is obviously damaged and disabled. But after the commercial break, the Town Car is back on the street, all shiny and new. No explanation is given.
Sorry, the writers and producers were way off on this story. I can only rate it 6 stars.
