This 1967 SyFy/Family TV show was so bad that it was downright terrible.
Its story of futuristic space travel was set 30 years into the future (1997) - And, now (in 2018) - Its story belongs 20 years in the past.
This truly inept family-drama is definitely for the entertainment of those who have really super-low expectations in their choices of vintage TV programs.
I lost track of how many times the ship's circuitry got fried, yet, as it turned out, everything was fine. It really killed me that there never seemed to be anyone ever manning any controls on the Jupiter 2.
And, finally - Speaking about this show's villain, Dr. Smith - He was an utterly detestable screaming queen. His presence, alone, made this TV show almost unendurable to watch.
