Lost in Space belongs on Netflix. The story of the Robinson family and their voyage to find a new world has universal appeal, and I can't wait to see how audiences around the world respond to this re-imagined version of one of the most beloved classic science fiction tales of all time.”

Toby Stephens said,

“As one of my all-time favorite stories, Lost in Space has always been one of the projects I wanted to work on.

“So when I heard Netflix was interested in doing a modern retelling of the story, with Parker Posey as June, I couldn't believe my luck. This is a dream come true.”

Maxwell Jenkins said,

“I'm so fortunate to be a part of this retelling of a classic story. I can't wait to see what my character goes through and how my relationship with the other characters changes throughout the series.”

What Is Lost In Space About?

Following the catastrophic event that threatens humanity's existence in 2046, the Robinson family is selected to participate in the 24th mission of Resolute (24th Colonist Group), an interstellar spacecraft carrying selected families and civilians to colonize Alpha Centauri.

Unfortunately, before they reach their destination, an alien robot breaches the Resolute hull.

Scores of colonists, including the Robinson family, are forced to evacuate the mothership in numerous short-range Jupiter spacecraft and crash on a nearby habitable planet.

In this strange environment, they must deal with the hostile environment and search for a way home.

Should I Watch Lost in Space?

This is a great family show that keeps you on the edge of your seat the entire time. As the Robinson family finds themselves lost in space, they must use their wits to survive.

This series will appeal to all ages from young kids, teens and adults.

How Many Seasons?

Lost in Space has three seasons in total.

Season one premiered on April 13, 2018, with the second season arriving on December 24, 2019.

Reviews Of Lost in Space

The movie review website Rotten Tomatoes reported a 68% approval rating based on 75 reviews.

The website review writes, “Lost in Space is a bold and ambitious production with deep space exploration as its backdrop.

“The story's heart adds an emotional anchor to all the drama, making it accessible for sci-fi adventure lovers or newcomers looking at this genre from fresh angles.”

IGN gave the first season an 8.5/10 rating, calling it “an excellent sci-fi adventure with a slight villain problem.” In my opinion, that's completely false.

Dr. Smith in the reimagined series is a much better character than the villain in the original!

Vulture described Posey's performance as Dr Smith as providing “underplayed, cunning comedic touches”, which is a much more accurate description.
