Many TV shows will, in the end, not be perfect with things like poor cgi, editing, writing and acting. For the most part, Picket was pretty darn good for the first
6 episodes before any major issue surfaced.
By episodes 7-9 the needed information or thing just started to fall into the lap of the good guys and the bad guys seemed to get dumber or suddenly acted out of character. Episode 8 went on way too long and episode 9 wrapped up halfway through.
There is a little environmental preaching in here and what little there is fits into the overall story and I don't feel like I have been clubbed.
Even with that the show was entertaining and I found myself liking the main characters. All of the actors did an excellent job, even the children.
I have never read the books but want to and I will be clicking on season 2 here shortly.
