Real short one.
The question was asked elsewhere: What’s your dream job?
Take Lost in Space only serious, ditch Dr. Smith, give them a robot with manipulators suitable for more than carrying an ice cube tray (since those are obsolete anyway), a decent ship with effective defensive weaponry, and instead of being lost the family is exploring. There you have it.
Hmm. So almost, but not quite, exactly unlike Lost in Space. 😉
