In an attempt to appeal to everyone, Netflix's Lost in Space appeals to no one. This show is rated TV-PG, so you'd think it's target demographic is younger kids and parents, however, it's quickly revealed that this is not the case. There are certain plot points and themes that are dark and (arguably) unsuitable for children. But these plot points and themes cannot be properly explored because of the the rating, so the show feels shallow and uninteresting. I wouldn't recommend this for families nor would I recommend it for adults. So who exactly is this show for?

Lost in Space also suffers from terrible writing. The plot meanders. The characters are dull and uncomplicated and unlikable. They make decisions that are baffling in their stupidity. The best (worst) example of this is Dr. Smith, a horrible one-dimensional character. She makes decisions that serve no other purpose than to create drama and conflict, and her motivation for her actions is never made clear.

The world building is lackluster. The space-tech is generic, and the planet they crash on is suspiciously similar-looking to Earth. This is one of the biggest wasted opportunities of Lost in Space--an alien planet could produce an infinite number of interesting plots, but the alien aspect is glossed over in favor of horrendous plot points and pointless flashbacks.

Conclusion: annoying characters and a stupid plot ruin a good premise.
