Really great cast, I enjoyed it. I haven't seen an entertaining series like this in a while. Just finished season 2. The relationship between older and younger generation is at play, adults are seen as very distructive to the earth, and humans children are forced to grow up fast, but hybrids are seen to be more in sync with nature. This is by no means a rational movie, the scientist who discovered the virus, and spent all her life trying to find a cure when she finally gets the opportunity to save humanity she bails out and this is seen as noble.
