23 best science fiction series

Science fiction series often mess with our imagination about the future. While some bring optimistic perspectives, but other problems that we don't even imagine dealing with yet, others show a planet Earth that ended up regressing, even with technological advances.

There are those that don't even happen on Earth, while others bring alternative versions of our planet, with another type of technological development. There are science fiction series that cater for all tastes.

Some of the best series ever follow this genre and are extremely popular. For a fair listing, we use as a basis the list of the best or most popular IMDB aggregator series, ignoring all those that do not follow the genre.

Because it is a very broad genre, in the list below you can watch series of almost all types, but always using science fiction as a background.

If you like to watch anime, you already have a reason to celebrate: the best rated science fiction series is just Japanese animation!

1. Fullmetal Alchemist: Brotherhood

Available between Netflix series, the most indicated series is the anime Fullmetal Alchemist: Brotherhood. Launched in 2010, the plot shows us a universe in which alchemy is capable of truly incredible feats. So much so that two prodigal brothers attempt the feat of resurrecting their mother using their skills.

However, the experiment went quite wrong, causing the youngest body to disappear and forcing the older brother to seal his soul in armor, making it incorporeal. Taking the blame for the failure, the protagonist's goal is to find a way to recover his brother's body.

Fullmetal Alchemist: Brotherhood has a rich history, full of interesting characters and a very creative universe, justifying its first position in the list of best science fiction series. Of course, it is worth mentioning that it is also one of the best animation series you need to watch.

The series is available on Netflix.

2. Beyond Imagination (1959)

One of the oldest sci-fi series in existence, Beyond Imagination continues to be highly regarded. Each episode has a different story, addressing issues such as alien abduction or communication with the supernatural.

Basically, each of these stories uses our own human characteristics to send us messages about how we behave and the consequences that behavior can have.

The classic version of Beyond Imagination is available on Oldflix, a streaming service specializing in old movies and series.

A new version was launched recently and already has two seasons. This edition is available on Amazon Prime Video.

3. Firefly

4. Cowboy Bebop

Another animation to be included in our list, Cowboy Bebop is an anime from the 1990s that is quite popular among fans of the genre until today. Set in a distant apocalyptic future, the drawing shows the routine of a band of hunters for hire, who chase criminals in exchange for a good reward.

That's because our planet was uninhabitable after a galactic accident. This expelled us from Earth and made us occupy new planets, increasing crime considerably. Demand has made rewards for capturing bandits once again a reality.

As a result, four characters who are not well integrated into society were forced to join and pursue this career. On the other hand, its licensing in Brazil made the exhibition of anime difficult, which is why it is not possible to watch it in apps to see films and series that we are used to.

5. Black Mirror

Even if you have never seen the series, you certainly know someone who watched it and at some point commented “weeeeeeeeee, this is very Black Mirror”. This is because the science fiction series takes an element of our existing technology and exaggerates it many times.

The goal here is to show how the misuse of technology can end up ruining our humanity. The possibility of recording videos at any time, star rating systems like Uber and iFood and the overexposure caused by social media are some of the themes covered in episodes of the series.

In general, each episode tells a different story, making it possible to watch loose episodes without losing any of the plot. Currently, there are episodes with continuity, so the ideal is to try to follow in a linear way. Black Mirror is available on Netflix.

6. Steins; Gate

This sci-fi animation shows a group of students who accidentally discover how to send messages over time. Using their knowledge about the future, they will try to destroy the plans of an evil organization, using the machine to send messages to their personalities in the past.

7. Battlestar Galactica (2005)

Despite having versions even in the 1980s, Battlestar Galactica became extremely successful with its 2005 series. Introduced by a film and a miniseries – spoiler: which is also on that list! -, the series shows the return of the Cylons, beings created by humans, but who turned against us.

After decades since peace between humans and Cylons was established, the Cylons mysteriously cease to appear in mediation sessions. Suddenly, they return, but with the intention of resuming the conflict against the human race. Almost a series of war with science fiction.

10. Star Trek: The New Generation

Thinking about the best science fiction series and forgetting Star Trek can be considered a crime. Despite not being the first series of its kind, the original series was one of those responsible for popularizing it.

Now with a new crew, the plot of the series follows the same: exploring space, the final frontier, going boldly where no one has ever been. All Star Trek: The Next Generation seasons are available on Netflix.

11. X File

From the same time as Star Trek, The X-Files doesn't have such a futuristic footprint. In fact, it takes place today. What makes it one of the best science fiction series is that it addresses one of the most common themes in the genre: the presence of aliens among us.

Following in the footsteps of detectives Scully and Mulder, they both have different approaches when it comes to investigating the series' mysterious cases. While Mulder is credulous in supernatural forces, Detective Scully is skeptical and approaches everything based on science.

One of the most successful series in history, the 11 seasons of The X-Files are available on Amazon Prime Video.

12. Battlestar Galactica (2003)

This is the miniseries that introduced the Battlestar Galactica series. With only two one-and-a-half-hour episodes – it can almost be said that it is a science fiction film – it serves as an excellent introduction to the other series.

Battlestar Galactica's 2003 miniseries is also available on Amazon Prime Video.

13. Neon Genesis Evangelion

14. Fullmetal Alchemist

Easy, you're not seeing repetitions here. Fullmetal Alchemist was released before Brotherhood, but it follows the same premise. However, there is a crucial difference that makes them different and justifies the inclusion of the two in the list.

While Brotherhood faithfully follows the line of the comics that originated the series, only the beginning of Fullmetal Alchemist is similar, going in a different direction. Although not considered as good as Brotherhood, the original animation is still of high quality.

With 51 episodes and also being one of the best fantasy series, Fullmetal Alchemist is also available on Netflix.

15. Doctor Who

16. Love, Death & Robots

This animated series from Netflix follows a format similar to what we see in Black Mirror or Beyond Imagination. That is, all of its episodes are separate stories, with little or no connection between them.

Unlike the Japanese animations mentioned so far, Love, Death & Robots is not a series that can be watched by children. The episodes are loaded with morbid humor, violence and nudity. It is worth noting here that not all episodes are animated, also featuring episodes made with real actors.

17. Mystery Science Theater 3000

An unusual mix with comedy series, Mystery Science Theater 3000 brings its own creator in an unusual situation: he is thrown into space on a satellite and forced only to watch B movies, accompanied by a group of robots.

Torture comes in the form of a lot of laughter for awkward situations, low budget films and poor performances that these films usually bring. Which generates virtually all the funny situations in the series.
