Like many other movies and miniseries about this topic, this work is horrifically bad. It was poorly written, acted, and produced. It is almost laughable how awful this thing is. This is worse than some of the bad science fiction movies that I watch for kicks. It sticks to a convoluted interpretation of the Christian apocalypse that opportunists like Kirk Cameron, Jerry B. Jenkins, and Tim LaHaye have used to line their pockets for years, but the overused plot not even the worst aspect of this thing.
The shaky camera style is reminiscent of The Blair Witch Project, which fits well with the other poorly executed parts of the miniseries. If you are prone to vertigo, migraines, seizures, or motion sickness, especially if these have been triggered in the past by past movies or television shows, you might want to avoid this for health reasons. If not, just avoid it for quality reasons. It's not entertaining enough to justify wasting so much time on it.
