Reading the individual issues, the major complaint I have about this series is that it's too short. It's sad that a series with such great storytelling and heartfelt scenes has to end after only five issues. But what powerful issues those are. From the start, Nathan Fairbairn took time to develop his characters and his plot. Characters like Sir Raymond and Hugh are likeable because they have some surprises up their sleeves and they wield real emotional power. Admittedly, Bernadette, the sole female character, is not as well-developed, though she is clearly a strong character. And the monk, the only villain that is human, is one-dimensional and what happens with him is predictable.
But that's not to say the emotional weight of the conclusion is lessened any. There's plenty to enjoy, from the scenes of humor to the wonder of the unknown, and the horror of said unknown. That the series is about an alien race that crashes into France during the Middle Ages seems silly, but Fairbairn plays it straight. The alien creatures are fearsome and frightening and the reaction to them feels right. That many questions won't be answered is only natural enough, but I don't want to say anymore for risk of spoiling anything.
The artwork by Matt Smith is quite good, enhanced by Fairbairn's coloring. Fairbairn sometimes opts to tint whole panels in reds or another color, but in most scenes his coloring is vibrant and helps bring the story to life. Smith opts for a realistic approach, perhaps to add to the credibility of the plot, as realistic as hand-drawn characters and actions can be, at least. There is a strong attention to detail, with a focus on character expression and on the gruesome when terror rears its ugly head.
The length is unfortunate. I wanted more. I wish Fairbairn could have spent more time in this world, but he doesn't rush his story much. It might be tough to justify the high price tag ($16.99 on Amazon for pre-order) at only 5 issues. Those who read it will be in for a treat, though.
