I’ve only experienced the initial season of this collection of stories, because the storyline for the subsequent one didn't appeal to me. Given my exposure to numerous books and documentaries concerning Arctic journeys, I understand how this show originated: the creator used the basic framework of John Franklin’s disastrous attempt to navigate the Northwest Passage and transformed it into a new horror narrative. That seemed interesting, and I was ready to enjoy it. This adaptation did an adequate job bringing the story to television. It functions as an acceptable horror story. However, when I noticed the phrase "Based on actual events" or something similar, I began to wonder why that was necessary. Typically, adaptations of true stories stay reasonably faithful to the original account, rather than fabricating a creature that eliminates real historical figures in ways beyond starvation, illness, and potential cannibalism. It makes one question why the story couldn't simply be presented as a horror tale without trying to appear connected to history. (For instance, I’m under the impression that John Franklin passed away later in the expedition than shown here with Ciara Hinds.) Regardless, my reservations and inquiries didn't diminish the suspense and emotional impact of the series. It was enjoyable, which might be its primary purpose, even if I found myself questioning it afterward.
