You can disagree, but I think the series is very well executed. It reminds me of Battlestar Galatica, in story ark and characters. Some people were comparing this with original 1968 series, and say there is nothing new here. But this is a reboot, not a new one. It is ok to reinterpret the series after half a century.

All characters are shown with flaws, and the story is about overcoming them and uniting as a family. There is no attempt to deceive the viewer as the series does not attempt to give surprises (all mysterious elements are revealed in the first three series), but these revelations help increasing the tension. I liked how Dr. Smith is portrayed. Unlike the 1998 movie, the antagonist is very manipulative, psychopathic and menacing in many ways.

I did not watch 1960s original, but having watched 1998 movie, this is a great step forward. Any reboot can be tricky, as it is near impossible to catch up with the original feelings. But it can try to generate the new one and this series deserves some credit.
