I think that’s because they preferred the show be more serious as the early B/W episodes were. The reason it turned “campy” and “cartoonish” was to compete with Batman.

Exactly. And the scripts tended to focus on Smith and Will Robinson. Season One was very well written.

Actually, what I said couldn’t have been correct since “Smith” was there from the very beginning (minus the unaired pilot). But it does explain why some of the cast were somewhat disappointed in the series following the switch to camp. Of course most of the silliness revolved around Harris’ character, Dr. Smith.
