I thought Halt and Catch Fire was fairly well known, especially in the tech world.

Season 1 was absolutely killer. I like that they tried to capture different eras per season, but subsequent seasons got progressively weaker.

I still think Gordon's final scene is one of the best pieces of writing in TV drama history. Took my breath away the first time I saw it.

It's fairly well known to some of us. It's one of the few shows I own DVDs of.
