Very good show. (I did not watch show originally because I was afraid it was just another CW young adult show with one dimensional characters, little plot, and too much emotional angst instead of a story. But that is definitely not the case.) Good characters and actors. Good storylines and more than one at a time, which I always look for. Good action, while also developing characters who are not one dimensional. Engrossing show, which is why I bought an additional season.

This is a great show. I have yet to watch it on tv but was hooked after the first episode!!

Strong women actors they make this show worth watching!!

I watched all the series,the young actors did a great job.

I have been a sci-fi fan since I was a lot younger. I read somewhere that this is considered a young peoples show sorry to bust someone's bubble but I think this show is GREAT and I am 60 years old. I know there is a difference between a tv series and a theater movie that being said I would rate this as being almost equal to star wars as far as being an entertaining sci-fi . I have yet to watch a tv series or movie that I agree with 100 o/o so keep in mind this series is made by someone else's standards and it is impossible to please all the people all the time "1 old man's opinion"
