Television

These don’t seem obscure to me but most folks I know have never heard of them:

What We Do in the Shadows

Sealab 2021

Parks and Rec

Party Down

Freaks and Geeks

Venture Bros

Raised by Wolves. It was killed by HBO around the time of the discovery merger thing, but was a fully written (creator originally wrote it as a book, and then made it into a screenplay) and unique show. Produced by and has some directing from Ridley Scott.

The show follows two androids, Mother and Father, raising a human child alone on a desolate planet after fleeing a dying earth controlled by hi-tech zealots. This new home might be far more related to them than they realize, and maybe not always so desolate. It blends mysticism and sci-fi in a really fun way, and I will never not be angry I don't get to see how it ends.

Galavant

Mighty boosh

Red dwarf

Misfits

I guess in this case obscure differs a lot geographically, but I definitely know places where they are almost completely unknown.

Reaper was a really brilliant, easy-watching action/comedy show akin to Chuck. It's centered around a young man whose family has sold his soul to the devil, and now he must fulfill the contract by hunting down souls that have escaped from hell.

It features the typical "monster of the week" premise, along with a longer story arc across the seasons and has a rather fun mythology and world building. Ray Wise puts in a phenomenal performance as the devil, and I remember the show having a pretty genuine and surprisingly wholesome sense of humour.

Sadly its momentum got interrupted by the writers strike, and its second season was shortened and then cancelled. I still highly recommend it.

"On The Air"

Wonderfalls

I did not see Herman's Head mentioned. I've only met one other person that remembers it. Not great in a change-your-doors-of-perception for life, but a fun sitcom from the early '90s.

Others have already recommended Pushing Daisies, Wonderfalls, and Galavant. All are worth another mention.

I'm surprised only one other person mentioned Final Space. At first glance you might think, "Oh, it's just a Rick and Morty knock off." You'd be wrong. It's much more Futurama in tone than it is Rick and Morty. I'm not afraid to admit Final Space is the only cartoon I've watched as a grown man that made me cry. On multiple occasions. It hits you right in the feels, hard.

I always mention this one, but The Adventures of Brisco County, Jr.

It's got Bruce Campbell in it (Army of darkness) And he plays a cowboy as the lead character where he goes on wacky steampunk-filled hijinks and adventures through the Old West.

it came out in the early 90s and you can watch it for free on tubiTV.

Fun fact, a lot of the old timey western movies used a particular set and the Adventures of Brisco County Jr. was the last show to use that set.

When they finished it was torn down.

Another fun fact, you've heard the theme song.

It's now used in the Olympics when America plays.

It's a fucking amazing show.

You're The Worst

-- A dark comedy / romantic comedy that centers on two toxic, self-destructive people who fall in love and attempt a relationship. --

Absolutely amazing TV show by Stephen Falk. Criminally underrated. It is my favorite show of all time. It should be available to stream on Hulu, otherwise pirating it may be the only way to watch it.

Kipo and the Age of Wonderbeasts

-- A bright, wonderful and adorable show (animated by Dreamworks) that follows 13-year-old Kipo navigating a post-apocalyptic world full of evolved animals with human-level intelligence, and making friends along the way. --

This is a family-friendly show that took me about 7 episodes to get hooked. I am so glad I stuck with it! Made by Radford Sechrist and Bill Wolkoff. It's on Netflix. It also had a small DVD release that may be difficult to find.

There have been a veritable ton of amazing shows from Adult Swim that flew under the radar. My three favorite are:

• Dream Corp LLC
• Your Pretty Face is Going to Hell
• The Heart, She Holler

The Lost Room.

Not sure where you can find it, though.

Lexx, a show about a giant dragonfly spaceship that destroys planets and the creepy cowardly idiot who somehow lucked into becoming the single person in the two universes that it obeys. And an undead assassin-warrior-poet. And a woman who survived a botched "love slave" transformation. And a weird robot head.

It's outrageously strange and strangely horny and hornily gross. Highly recommend if you like weird TV.

Pushing Daisies

Dead Like Me

It was pretty much all over the place but I liked the tone and premise. IMO, I really doubt anyone would've been able to make that kind of story work any more than the original folks did but yeah. I don't think the writing was that good but I liked the cast. That alone would've sold me. Also maybe throw in the fact that I found the show while I was kind of starting out on my own during college and so in ways, I related to the main person. Yada yada yada.

Monkey Dust. BBC show from the late 00''s that went ~3 seasons. Animated sketch comedy that was ostensibly British but wasn't SO British that Americans wouldn't get it. Example sketch-

Mr Inbetween is an excellent Aussie show. Haven't found anything else that captures our culture so well.

Not sure where the bar sits for obscure / under the radar. There's plenty of more popular shows I normally recommend.

Keeping it less known I guess:

Sense8 - slow start but cool concept

The goes wrong show - brilliant little piece of British theatre humour. Some great recurring gags

And second another commenter's recommendation of you're the worst as a good laugh.

Spaced

Early Simon Pegg / Nick Frost / Edgar Wright collaboration, sitcom style.

The Almighty Johnsons

Cleverman

Haven

Charlie Jade
