There are some long running plot lines, but for the most part it’s much more episodic. Curiously it retains much of the TV format, including a title sequence introducing each character. It’s hard to imagine a viewer “tuning in” to the middle of the series and needing such an intro. All the episodes are available online; why would anyone not start with the first?
Amazon also had a one season run of a show called Betas which I thought was nearly as biting in its parody as Silicon Valley. Amazon may not yet be a first rate producer, but I’ve been impressed with the quality of what they’re turning out in tier two.
