Even as an under 10 year old I hated LIS. I agree with the B&W episodes being alot more atmospheric and i also love the robot and chariot.
And as a few have said--it's a very workable, decent concept that just got stupider and stupider as Dr Smith took over the show.
It runs on 'Me-TV' in my area and every time I happen to pass it while channel surfing---I see the kid and Dr Smith.
So either I am seeing a huge un-representative coincidence of time spent on those two or they just drove that dynamic into the ground!!
