I really loved the initial episodes with the superb CGI giving us stunning world making with mesmerizing landscapes. The fundamental story is based on the Robinsons family, space colonists who are as you may have guesses lost in space. Most of the storytelling is about them facing life threating situations, overcoming it in innovative manner and coming closer as a family. It's all sweet and makes them instantly likable, each of the members have their own quirks and we can't help but root for their survivable.

As the series progressed and other humans are introduced, the series becomes lamer, especially with the plot line on Dr. Smith. Her characteristic and storytelling fell under the grey area for kids and outright silly for adults. In my opinion, if they had kept the story focused on just the Robinsons vs Inhospitable Planet/Space, it would have been more entertaining, we didn't need a human villain.
