This is a great show...with great actors and good performances. I'm still watching the series and I do find it enjoyable and bingeable.
The only gripe I have....is the occasional frustrations with the science (I've seen better ones out there, but I also recognize this show is better than others), but likely the most frustrating aspect of the show, is the amount of stupid decisions made by most or all the characters due to lack of communication, or stubbornness with honour and tradition. Also, the characters do jump from being moral, to immoral quite frequently or friends to enemies (and lots of backstabbing) which tends to get frustrating for me. However, at least the plot writers did a good job of tying things in and making it believable for that world. But its like a well-acted soap opera.
I can also state that the characters are overly attractive for who has survived the world. And for a show that has that many attractive characters, I'm impressed they managed to make a show with very little nudity and sexual content. There is a lot of teenage angst and feelings along with thoughts of self-harm which was surprising, but I'm sure a younger or teenage audience would find it relatable to that generation and what they go through during those times in life. Either way....it's a good sci-fi show overall as long as you can get over the highly dramatic aspects of the show.
