This show is about being stranded and working together to get back into space and travel, life becomes tough for the Robinson family when the space rocket can't launch, lots of hazards with the engine starting, it is really good and fun to see how they will get the spacecraft or rocket going up again. That with the presence of a machine type alien who Will and also the family members are unsure what to do with it. This show is very good when they have to rebuild and is also fun when they complete their jobs and are allowed back on the crew, it was good to see some members make big changes from being bad people.
