This is definitely a family series. I found that aspect of it irritating as it made everything dangerous and interesting about being actually lost in space a setup for family dynamics. The character of Dr. Smith (in this version a woman) is so nefarious and yet gets away with doing a number on everyone over and over again.
If you like science fiction this will not satisfy. It is about a family in endless peril but having the time of their lives.
I gave it three stars because it looks good and it is family friendly for all those families out there trying to steer clear of the walking dead, Game of thrones and stranger things.
Also just so we are clear I thought the original Lost in Space was totally lame.
