Lost in Space is an exciting space-travel show (based on the 1960s show) with a surprising Christmasy theme. To be fair, I do not recall a single time in the Netflix series Lost in Space where they mention Christmas. There are no religious undertones within the show either. In fact, it’s a very decidedly humanistic message that focuses on the strength of character and intellect to win the day. Despite this, there is a clear “Christmas Carol”ian theme–the possibility of change.
