Most Terence Malik films I guess? He's popular amongst film buffs, but I feel like his reach should be broader than that.

Darklands (Video game)

It came out in 1992. Set in the 15th century Holy Roman Empire / Germany. It's a 4-character party isometric game that featuring real time combat, party members who aged and would die from old age, perma death, and fantastical elements based on historic folklore, Catholic saints, and alchemy.

Corncob TV: Just hours of naked, dead bodies busting through shit wood.

I never heard anything about ‘Crashing’ on HBO before just stumbling on it in the HBO app.

It’s a pretty funny show about a standup comedian trying to make it in NY while dealing with a divorce. It kind of feels like Louie if the protagonist had a positive outlook on life.

It’s not the greatest show ever, but it blows my mind that I’d never heard of it at all

I grew up playing the 3D version of Centipede on the Sega Dreamcast. The game was a fundamental part of my childhood.

For whatever reason, I've never spoken to even a single other person who has ever played it (aside from my brother).

The level design was crazy. Tons of replayability, a low barrier to entry, but so difficult in the later worlds I never got close to finishing it. Soundtrack and sound effects I never got tired of hearing. Yet, no one seems to have heard of it.

The Nice Guys deserved more recognition for sure.
It had little no advertisement at all and it was overshadowed by a lot of other movies that came out that year: La La Land, Deadpool, Rogue One, Split, The Founder, Captain Fantastic... These are just some of the big titles that came out in 2016.
The only reason I saw it was because they put it on at my local movie theater one evening that I had nothing better to do: I went in with low expectations and came out having seen one of my top favorite movies ever.

The Truman Show. Very underrated, but its not brought up often.

Farscape was an absolutely fantastic show with one of the best villains ever. Characters were well thought out, they had motivations you could understand and showed character growth. Highly recommend for anyone who hasn't seen it.

Inglorious Basterds. This movie is well-loved and has widespread appeal, but I feel like it doesn’t really have the respect that it deserves. I feel like Pulp Fiction, Django Unchained, Kill Bill and even Reservoir Dogs have had more cultural impact, but Basterd’s is, imo, the closest Tarantino has come to a perfect film.
