Lost in Space is an enjoyable, well made series. The production value is incredibly high, and the wide shots of vast landscapes make for a visual feast. The quality of effects on the robot and spacecraft is also commendable. The characters are all pretty good, and the relationships between them become more clearly defined as the show goes along. The initial intrigue and mystery of why exactly the characters are in space, and the origins of the robot keep the viewer engaged. The main characters are almost always in danger, creating a sense of urgency as well.

Where the show is more frustrating is the plot itself. Because the characters are always in danger, and there always seems to be some big spectacle taking place on screen, little time is devoted to developing any sort of plot within each episode and throughout the season. At the end of every episode the crisis is averted, of course only for some new problem to pop up in the next one. Getting to the finale, some semblance of a plot is quickly set up a couple of episodes in advance before being quickly diffused. This is where the show suffers and what holds it back greatly.
