Very interesting concept of the future of humanity! The story line is a fantasy, making it an eye opener for all choices to take during a war. From leading to surrendering and from betrayal to forgiveness, this series is entertaining and full of many mysteries that will keep you wondering, "the what ifs..."
The characters are well balanced. Octavia is my favorite character. During 5th season, this character becomes very dark, and makes you cringe, every time she opens her mouth. Raven Reyes is another character that I like very much, but I feel that they should give her more depth. Bellamy is the "good guy", while John Murphy, is not. I love the balance of characters that they bring to the series.
Interesting points for the writers; the thing with series is that as further on the series goes, the more it separates from the original goal from where they started. In this series, this does not happen. What it does is that it gives the same goal with a different perspective. When you think you know what's about to happen next, it takes a total different turn. I love this most of all!!
