Halt Catch Fire - which is four seasons, and aired on AMC about a year or so ago. It's available now on NETFLIX.
It's tighter than most - in part because only four seasons, ten episodes each season, and five main characters, with about three recurring supporting characters. With possibly the best series ending I've seen. Because it is so compact, it manages to swerve some of the pitfalls and missteps that series like Game of Thrones, Breaking Bad, etc - fell into. Let's face it - when it comes to television series - four-five seasons is best, and the less episodes, the tighter the story.
Halt Catch Fire is character centric - focusing on the arcs of a computer engineer, visionary, and prodigy coder as they join together to create new technology in the 1980s and 1990s - at the start of the tech explosion.
The series also acts as a fun history lesson of the early age of the tech industry. It's accurate. I worked in the industry from 1997-2007, in various guises, as did my brother and various family members and friends. Some still do.
It takes us from the earliest conception of the lap-top computer through internet security, broadcast servers, game development and finally net browsers. Showing how the attempt to create comes with its pitfalls.
Also, as my brother put it, it's a rather subversive model in that they keep failing.
( mild spoilers )It also worked as another television series I could discuss with my poor mother. Who just watched Black Panther on Disney Plus and loved it.
