My family has watched the first 4 episodes together and enjoyed each one! We all love Penny - side note, the three Pennys have been one of the best things about all three versions of Lost in Space! This Penny owes more to the movie version then the original, but then Penny was the best thing by far in the movie version. I thought it was interesting that the first episode credits mentioned that it was based on the first episode of the television series "The Stowaway," I don't think I've ever seen a reboot of any television series refer to being based on a specific episode of the original series. You can definitely tell that this series is based on the first black and white season of the original series, before if became the Dr.Smith show in later seasons..
