Netflix’s Alien Worlds Review: Life Here and Out There

Alien Worlds is a Sci-Fi documentary series narrated by Sophie Okonedo. It consists of four 45-minute-long episodes.

If, at any point in your life, you’ve been fascinated by the possibility of alien life, then you’re in for a treat. No, I don’t mean the green stick figures with bulging eyes that poke humans and abduct them. I am talking about actual possible extra-terrestrial life, much like the species on our own Earth. These species might just be living and breathing in some other planet in a world much like our own in another galaxy.

Alien Worlds uses science and fiction to give a comprehensive and very possible depiction of what alien life might look like if they exist. The series, consisting of four episodes, provides in-depth analysis into the world of science and uses fiction and animation to give birth to a world which seems too good to be true, but can definitely exist.

The series analyses a variety of different species, from ants to human beings to birds, and dissects their various fascinating behaviours to give birth to amazing fictional species in different planets around the galaxy which might just exhibit similar behaviours. So, if that were the case, how would they behave? Would they hunt, reproduce and live the same way as the species from our planet? These questions, and many more, are what the series tackles.

Alien Worlds relies heavily on animation and, honestly, an overactive imagination to give birth to scenarios that are fascinating to behold. Although, trigger warning for all those who suffer from Trypophobia, some of it might just be very uncomfortable. The species, whether it be minuscule or huge, are thought out with much precision, making watching this entirely believable. Add to that every situation is proved with the help of similar species on Earth, and you have a series that makes you believe in the impossible.

On the other hand, the animals that we see on Earth are shot and discussed in-depth and everything is very nicely explained. Even if you don’t want to believe in alien species in another galaxy, it’s fascinating to look at Earth’s many wonderful flora and fauna that you might not have known before this.

The animation of the series is absolutely wonderful and adds a lot of realism to the experience. It feels like you are on that planet, looking at these animals and experiencing what they do. However, Alien Worlds isn’t about that. It tries to analyse what kind of life forms might exist outside if they follow the same principles as us. It analyses their possible body structures and habits and backs it up with scientific facts. There are a certain realism and relatability factor to it and it’s amazing to wonder that this is, at the end of the day, fiction.

We follow four different exoplanets – Atlas, Janus, Eden and Terra and the possible species that might live there, along with following the different species on planet Earth. If you’re wondering how these two things might co-exist, then Alien Worlds has fascinating answers for you.

Additionally, Sophie Okonedo’s wonderful narration guides you through the intricate world of this planet and others and is a mixture of calming and mysterious at the same time.
