Here's where I think the series was going. Of course the Robinson's were going to visit different planets and areas of space where they'd interact with different types of aliens....something akin to Star Trek. I believe that the relationship between Judy and Don would have been WIDELY explored. I can see the turmoil there knowing that John would not be too crazy about the relationship. Remember in the pilot, when Maureen told John that Judy was having boy problems? John answered her by saying just point me in the right direction and I'll kill him. Plus the fact that Don is scared witless that John will discover about his and Judy's amorous past. Will's job would be the same as in the original series. He'd be the character that the younger/child audience would identify with. Will wouldn't have Dr Smith, the Robot, or Penny to get in trouble with...but we see he is a genius and quite curious....this alone could place the Robinson's in the same circumstances as in the original. Will going off...of doing something he see's as scientific...but places the Robinson's in jeopardy. The Robot would have evolved in time into a character all it's own...quite different from the Robot in the original. I think he would have been more of an android...and would have been robotic, but have the appearance of a human. I think he would have eventually been close to what "Data" was on Next Generation. Unfortunately, Penny is only an infant...so her part would have been greatly diminished in this version. Maureen is a doctor and scientist... she would have had a greater part to play in this version...they would have depended upon her greatly, not just because she was the mother...but because of her importance of being a medical doctor and a scientist. John was a military Colonel and experienced military leader. In command of the Jupiter II, he would have had the same expectations as any captain of a ship. Think of Kirk, Janeway, Piccard...except he has the excess burden of the responsibility of having his family aboard. Now about David. Just what happened to poor David? This alone would have kept me watching...especially since John insists that he will discover a way find David. It's possible that David could have been captured and brainwashed by the aliens. Sort of how Picard was with the Borg for a short time. I read on another thread that the Doctor Smith character was too important to leave out. I personally didn't miss him although I was a fan of his in the original. I personally believe that David is tied into the alien and Smith subplot. I'll post my feelings about Smith...and what part he may, or may not have played in this potential series.
