It can be hard to slog through the plethora of mediocrity to find a truly good sci-fi and fantasy series, but finding a truly good one can be nearly life-changing.

Save some time by checking out some of these series if you're looking for something with substance.

Redditor Apart-Scale asked:

"What science fiction or fantasy show is worth watching?"

Red Dwarf

"Red dwarf if you want a comedy"


"Rimmer: go to red alert"

"Kryten: are you sure sir, it does mean changing the bulb"


"Yeah but they were sometimes also deadly incisive."

"Take 'Thanks for the Memory'. As a drunken lark, Lister gives unlucky-in-love Rimmer the memory of being involved with a girl named Lise Yates. Happy at first, Rimmer eventually figures out that none of this ever happened to him but to Lister. Even knowing this, Rimmer remains devastated because 'The woman I loved most in the whole world ... loved you.'"

"The whole sci-fi trope that 'you are what you remember, so be careful fucking with it' - never seen it put more clearly. When it was good, Red Dwarf was amazing."


"I don't think I've managed to cook seafood in my whole adult life without singing 'I'm gonna eat you, little fishy!' at it."

"Cat is truly an inspiration to us all."



Utopia (UK)

"Utopia (UK). very good and very underrated."


"This is absolutely the correct answer. It's worth watching for the music alone, some of the most deeply unsettling audio you'll ever hear in your life, reminiscent of that one creepy alien song from Annihilation everyone keeps putting in their spoopy TikToks. Cristobal Tapia de Veer (what a fuckin name) is a criminally underrated composer, and this is his best work by far."

"The opening scene perfectly sets the tone for the rest of the show: quiet menace, deep dread, utter callousness, and the insinuation that all life is cheap and disposable, even that of children. If you like that scene then you'll love the show, although "like" might be the wrong word."

"While it ended sooner than the creators wanted it to, leaving plenty on the table for further exploration if they ever decide to bring it back, the story is fully complete and doesn't leave you with massive blue balls like so many shows that have been abruptly cancelled. And it's a show that will stick with you for years, made all the more relevant given the situation the world is in at the moment."



The Expanse

"The Expanse. So good."


"It's like a game of thrones in space only the books are essentially finished so it doesn't get the sharp drop in quality."


"One of the most important things about The Expanse is that the book writers are actively involved in the show's production - they're executive producers and write the script. They acknowledge weaknesses in the books and adjust the show to improve the plot and narrative. They also allow the characters to develop organically and take the actors' talents and insights into consideration while writing the show (for example, Drummer and Ashford were both given bigger roles in the show because the writers were so impressed with their performance)."

"They understand the source material better than anyone, which is why Season 3 was basically two books condensed into 10 episodes, but it was still so good. And they aren't hung up on their own egos and let the universe and characters take a life of their own."






"And Warehouse 13!"


"I just started watching this week, and I love Eureka! Already binged the first two seasons. It's refreshing to see a generally positive storyline that is pro-science without being dark and dystopian."


"I love that show. Jack carter saving the town from b movie sci fi conundrums caused by out of this world science projects gone wrong. His only tool to fix things…. His 'every man' logic."



Stargate SG-1

"Stargate SG-1. 'Window of Opportunity' is the best episode of TV I've ever seen."


"SG-1 will always be that show. I grew up with it and I’ve rewatched the entire show at least five times since. Last year my husband and I watched it together, first time for him, and he agreed that it was one of, if not the most enjoyable tv show of all time."

"The cast has great chemistry, not a single episode is a serious dud, and as a young girl it was an absolute pleasure and privilege growing up with Samantha Carter as a female role model."


"Atlantis too"


"Even universe is okay, but SG-1 is the best."




"Dark is my favorite show of all time. It’s a Netflix original and in German; it’s a time travel show that fully embraces the paradoxes a lot of other media dealing with time travel tend to ignore or avoid. It’s a truly beautifully complex show with some of the best and most shocking twists I’ve seen on television."

"The casting is also absolutely phenomenal. The show spans over 100 years and shows multiple generations of characters. Younger and older versions of characters genuinely look like the same actor at different points in their lives."


"Dark is amazing. It's also one of my favorite shows ever, and the only show that I've ever had to (and been willing to) take notes and refer to character charts while watching haha. So complicated, but so good"


"They really do! There were times where I thought maybe it was the same actor in good make up."

"Great show but I recommend marathoning it. Don't leave gaps between seasons or you may get confused. It's a show you need to pay attention to."



Babylon 5

"Nobody mentioned Babylon 5? It’s a little old, but that show has some of the best space opera storytelling out there!"


"Not only is B5 fantastic, original and pioneering, it's getting a update/reboot from the original show runner soon! Can't wait to see B5 in a modern reincarnation."



His Dark Materials

"His Dark Materials. If you get hooked, the 3 part book series is insanely good. Would NOT recommend the movie though, complete trash in my opinion."


"By far my favorite trilogy. I stopped halfway through the second season I just didn't find the characters fitting for the roles they played. I guess the story become to personal for me the way I imagined it from reading. Lee Scorsby Grumman, and even Will or Lyra all just didn't fit and it took away from the immersion. The episode where Lyra first gets to the north I thought was excellent however."


"My favorite book series! I’m very pleased with how the show turned out as opposed to the movie."



Dirk Gently's Holistic Detective Agency

"Dirk Gently's Holistic Detective Agency"


"It was a mind trip! My mum and I started it while having dinner, and we were so confused and intrigued we kept going. It hit midnight and I just wanted to go to bed BUT THE DOG?? BART!? We ended up watching the whole thing in one sitting 😂"


"So glad someone mentioned this show. Great cast, good balance of comedy and drama, just weird enough not to be off putting. Could have gone many more seasons"




"I’m shocked at how good Arcane is."

"since so many people have either commented that it’s the best series ever or highly overrated, let me say the obvious: it’s not for everyone. I understand many of the criticisms, and would disagree with anyone who acts like it’s perfect. It is pretty original and well-produced."


"Arcane is amazing! That show shocked me since I’m not at all into league of legends and I really ended up enjoying it! It’s also great to see the animation medium expanding out into more diverse styles and genres!"


"If anybody is avoiding it because it's animated and loosely tied to a video game they are missing out big time. It's the best fantasy TV series since the early seasons of GoT."

"Well written characters with great voice acting, great attention to detail and rewatch value, and possibly the most aesthetically stylish TV show ever."



If you're a sci-fi or fantasy fan and haven't watched some of these series, consider giving a few of them a try.

There are some really excellent shows that you might have missed because they didn't get a lot of hype.

Adulthood has been pretty nice, I have to admit. I quite like it. But it isn't always easy and some lessons are more difficult to learn than others.

It's so important to learn how to budget, for instance, because being an adult can get expensive. Between rent, food, utilities, and other odds and ends, you'd be shocked how quickly money flies out the window. Understanding this (and keeping an eye on your finances) pays dividends in the long run.

But that's also assuming things go well or smoothly – unexpected expenses arise and those come with their own consequences.

Countless men and women think hands and forearms are the sexiest part of a man, which is why many people are over the moon about the sight of a man in a button-down with rolled-up sleeves.

If you've not a single clue what people are attracted to, then have a look. You'll be surprised some rolled up sleeves, form-fitting T-shirts, and a well-tailored suit can take you.
