I remember watching the premiere, and intermittently some of the episodes (it was one I had to sneak to watch). Poor substitute for Star Trek. :') When the 'reboot' movie didn't result in sequels or a new TV series, I was pretty glad about it.
I thought Lost In Space was a very funny and entertaining series, as ridiculously silly as most of the episodes were. Star Trek, which was not really meant to be funny, as LIS clearly was, was a different type of thing. I like and watch both still to this day.
