As a Virologist, I have always found the concept for the cause of vampirism been a virus to be quite innovative & not outside the realms of possibility.
With that in mind, I found V Wars quite interesting. The polar regions are vastly unexplored territories so we don't know what lies breath them. So, the beginning of Episode 1, where the Prion existence for causing a virus infecting people with a disease that turns them into vampires is a great way to start a plot, that can offer many different angles for which the story can go.
While the plot turns out to not be as strong as I first envisioned after Episode 1, the ensuing episodes do makes an interesting story of humans ingenuity to combat the virus in every shape or from.
I found V Wars very entertaining. The characters could have been individually explored in greater detail, so as not to become mere caricatures of the actual plot.
But the story is enjoyable enough to provide solid entertainment. The episodes do flow well with interesting stories.
I hope there is a season 2 so that the plot & story can be further developed.
