Bored on the first episode, I almost switched it off, proceeded to ep.2 where all the actions started and got addicted until the end. It has a very good zombie plot. There are directions showed by the series where the survivors are trying to do. This is clear and much better than the Walking Dead. Hopefully the series will not get into the loophole of prolonging the ending like in the Walking Dead. That'll be a tragic. Worth watching even though, there are loophole in the plot. Why the Commander had to order the bombing of Hyoson in stead of barricading the town and search for more survivors. Why abandoned the students at the school rooftop, when they are rescued and quarantined the group later, etc. The rest of the series seemed reasonable and awkward at time. The director tried to pull out several good points and bad points in human nature which was obviously working.A must watch series.
