Mina's Character is awful. Only distanced in her absurdity by "Dr. Smith," who seems to not have a plot line that doesn't involve subterfuge and deceit. It's fairly annoying watching everyone's oblivious handling of their idiocy.

That being said, I otherwise really enjoy this show. The science is hokey, but so was the original. If you can suspend your disbelief (as in all sci-fi shows) you're sure to enjoy the cinematography at the very least and possibly get lost in the saga that is the Robinson's adventure.
