The story is not original, but at least is interesting and the concept is good. Although has not many connections with the old Lost in Space, still could be something to watch with fun and stuck with it.

BUT...... the script is soooooo awful it makes you wonder. Its not bad that they writers of the series made men seem stupid and women be in the lead. Its not bad that they are many cheesy dialogues and not direct things. The really bad is the story line and the actions of the characters. I managed to watch all Season 1 and in every episode i was... "Why??? , Really??? , Why they stop fighting and talking? , Why they dont see the obvious? " and many other questions that made me feel like its a low IQ show. And most of the things happens for no reason and others just with "magic".

The acting is decent. I disagree that people dont like Dr. Smith cause she is a character that you have to hate. And she manages great. The kids acting best they can according to the scenario. Its not the actors fault that the script is sooo bad. I like the flashbacks to get the story of its character but its an old trick and could be done in a better way.

Conclusion: change writers and the show can be great.
