The 90's film added depth without changing the characters from what they were to start out with. Again, I'm not saying this show is bad. I'm up to episode 5 now and will keep watching. It's a pretty good show about a family Lost on a Planet, and the survivors of a mission to Alpha Centauri. But it's not Lost in Space. They should have just changed the name of the family (NOT the Robinsons) , and called it Lost in Space: TNG, and it would be all good.
It's kind of like if in 1987 if TNG was just brought back as "Star Trek" plain and simple, with no reference to anything else, people would have hated it. (And I'm not talking about the initial hate of original Star Trek fans, I mean , it never would have caught on and been successful).
There are no more good TV Shows, only ones that haven't disappointed me yet.
