Well first I just want to say wow to the cinematography/CGI. It never gets old and is amazingly detailed.

Although Lost in Space does have great action it gets old quick. The emotion is good, but sometimes (season 3) that emotion comes with the cost of silliness (I almost never judge something on TV to have a silly idea or silly plot). And the emotion we get from Lost in Space that isn't silly is hard to come by, though you can still find some of it throughout this show.

But the best thing about this show is Dr. Smith. Every time she does something it always leaves you thinking "Dr. Smith, not again" and "can somebody just kill her?!" But that's why this show actually stays good and not repetitive. If you think about it Dr. Smith and uh, "what she does" is the only thing in this show that never gets old and is never repetitive.

At the end of the day I would only recommend Lost in Space if you are in desperate need of a TV show.
