Science Fiction

A couple of others I haven't seen here that I loved:

• Almost Human - Cut short, but had so much potential. :'(
• Foundation - Adaptation of Isaac Asimov's Foundation series. So far it's incredible, and the way they're stretching the story it could be 6-7 seasons.
• The 100 - hear me out - It's teen drama at first, in a sci-fi setting. This one reminds me of Orson Scott Card; focusing on how people behave in a futuristic sci-fi setting, not necessarily heavy on the setting. It was goofy, dramatic, sometimes cringe, and has huge plot holes - but damnit it was entertaining and jumps the shark soo many times.
• 4400 - Such an incredible premise for a show.

Some comic/hero shows that could technically count as Sci-Fi:

• The Umbrella Academy
• Legion - this one surprised me. It was amazing, and I didn't realize it was an x-men story at first.
• Agents of S.H.I.E.L.D

I think I'm the only person to ever watch all of Andromeda. It was not my favourite show, but there was something comforting whenever i was watching it. Maybe it just reminded me of the old Hercules, but in space.

In the spirit of the question (not picking the most common ones), I'd say Sanctuary was good. I think it was very (very...) low budget (everything is green screen) but the stories were great. There are a lot of fantasy elements but I think it's very scifi.

As my username suggests- I love 'Lexx'.

It's beautifully sleezy sci-fi fantasy and not nearly enough people know about it. I caught it on Netflix about 10 years ago but I think you can watch it on youtube now free with commercials.

Highly recommend to any fans of sci-fi, but especially if you loved stuff like Farscape and Red Dwarf.

Also shout out to 'Avenue 5'. Hilariously dark sci-fi comedy that HBO criminally underpromoted. Also 'Other Space'.

The Adventures of Brisco County, Jr. At the time, I couldn't understand why everybody preferred that boring FBI monster show with the monotone lead actor.

Lesser known but amazing you say?
Total Recall 2070
Wild Palms
Terminator: The Sarah Conor Chronicles

Big Hero 6. Seriously, I love the franchise.

no love for 12 monkeys tv series? great series

For a long time my answer would've been Doctor Who - I was an original Who fan who got hooked on PBS in the 80s and kept the candle burning in the 90s and early 2000s with books and Big Finish audio dramas. Now that it's back and more popular than before though, I don't know if it'd really count as "lesser known" like it used to, so for that criteria I'd have to say... Blake's 7

I wouldn't say it's my favorite, but I liked Humans (2015).

I also like several Black Mirror episodes, but I think those are "well known".

Since The Expanse has already been covered, gotta go with Firefly. I have a couple of the books on my bookshelf at work but I haven't gotten to them.

"Moon" was quite good.

It would be Netflix's Lost in Space for me. Love that show. It's got such a well-written plot and great characters, I'm so sad that not many people have seen it. It's only three seasons too.

Firefly will never not be my favorite. Truly before its time... imagine how many seasons it would have run for if it were made today and on a different network...

Counterpoint, amazing spy thriller Sci-Fi.

Spacehunter: Adventures in the Forbidden Zone. It's a solid example of 80's scifi, post-Star Wars and pre-Matrix. A little cheesy, a little Mad Max-y. And Molly Ringwald still makes me laugh.
