The first series is bad. There, I said it. Bad script, bad acting, annoying over the top smart kids. I gave it a 6, but, wait for it, there's a twist here because second series is actually much better, in the 8 range. After such a poor script in the first series I wasn't expecting much from series 2 but I said hey, these people had some great CGI, poured in a lot of money, let's waste some time seeing what they come up with. And come up they did. There's way less overly smart infatuated kids here, less running around fixing silly stuff and even couple good jokes pointing that there's always trouble finding the Robinsons. And most of all less bad decisions. It does get a bit corny in the final of series 2 unfortunately but hey, better than corny all the way. So, all in all I'm looking forward to see series 3 now, while after series 1 I was unmoved. So I guess it just became better, which is great, because this show actually has a lot of potential.
