This is a decent enough episode. It keeps you entertained while laying out the stories of strange occurrences in Alaska. I realize the answer to all these stories won't be revealed at the end as encounters with UFOs/aliens would have no definitive answer. If one was provided beyond a shadow of a doubt, that would be headline news!
I do have one complaint about the story of the doctor removing the tracker that had been implanted in the man's leg. The story should have included what was done with that bit of alien technology after it was removed. I would think there are people out there who would love to analyze it, but we never learn what the doctor did with it and what the results were.
Other than that, this show holds your attention and I recommend it if UFOs and aliens are your cup of tea. It is thought provoking if nothing else.
