Yes, Blood Trails is a prequel to the movie 30 Days of Night. But it also assumes you have some knowledge of the 30 Days world outside of what was in the movie. With these two things in mind, this is a great mini-series. The format is weird and annoying to be sure, but even so in each 3 or 4 minute installment there is still plenty of suspense and blood. The only thing missing is the eerie quietness of the movie, but considering the location of the mini-series it is probably a good thing it has a slightly different feel.
