The first episode was good and I was excited, thinking that I had found a decent series. However, as the series progressed, character development ground to a halt and scenarios silly/unrealistic. The female lead is charismatic and plays the part well - but all the other characters are so flat and dull. The relationship between the female lead and her son could have been really interesting and layered - yet the writers completely missed the mark with it. There were so many times throughout the series where the characters escape danger - when realistically they would have just been killed or captured. Also, there is little exploration of the 'impending doom' that forms the backbone of the story which is a shame. Overall, the plot holes, flat characters and other irregularities detract from the series to such an extent that it becomes frustrating to watch.
