• The Terror (First season only) (Horror TV drama)
• Death Parade (Anime)
• The Duchess of Duke Street (Older period drama)
• Oshiete! Galko-chan (Short anime)

It's not exactly "unrecognized" because it's fairly popular, but From -- yes, that's the name, and yes, it makes it very difficult to search for.

It's pretty highly rated, horror/mystery show. It's a lot like Lost except more horror less mystery. It even stars Harold Perrineau who played Michael in Lost.

The concepts and monsters are very scary and/or creepy. It gives me a Dead by Daylight "The Entity" and "The Entity's Realm" vibe if you're familiar with the game.

If you like para-military actions I highly recommend Spec Ops: Lioness.

Lioness is a CIA program who recruits military women to infiltrate terrorist organizations and destroy it from within.

It's currently on its second season. Zoey Saldana is fantastic in the show.

Farscape

A largely forgotten show from the late 90s called "Seven Days".

Most likely I'm too specific about it, but I see quite some shows mentioned that I'd not really consider underrated or unrecognised. Firefly is one of my all time favourites but not really underrated or unrecognised. Or Fringe, possibly not even From (of which I'll just say I very much hope they have an ending planned because I don't want it to end lost like Lost).

Perfect examples of underrated or unrecognised shows are Galavant and Utopia, mentioned by others, they are brilliant.

In a similar direction I'd say Dead Set, a UK show that really surprised me ages ago but never see mentioned. https://imdb.com/title/tt1285482/

Maybe I should include also Dr Horrible's Sing Along Blog, but that may be a lot less underrated and it's a minishow only.

Gary and his Demons is a great animated show that no one seems to have ever heard about

The Boy's Word: Blood on the Asphalt

Not "unrecognized" in Russia, but Woids are missing out

I don't know if it was actually under rated or unrecognized where it aired, but as someone who was trawling for TV to watch that you don't see in North America, I fucking love Monkey Dust out of the UK.

Dark comedy animated sketch show.

3rd rock from the sun

Newsradio (RIP Phil hartman)

Growing up, I loved Tattooed Teenaged Alien Fighters From Beverly Hills. Now that I’m old, it’s even better.

Black Sails Occupied (Okkupert) Orphan Black

I don't think it is very well known, but I thought Scavengers Reign was very good. It was a bit slow, but I thought it gave time to see the weird alien world.

If you are on the fence about it, the show is a followup to this short and has some similarities in its world building.
