The first season was the weakest. Seasons 2-4 are some of the best television ever IMHO. Once they stopped trying to make it Mad Men with tech, they freed themselves up to succeed.
This too (and I know I'll get flack for this one) seemed to be the case with Jobs and Wozniak, Wozniak is an undisputed genius on both hard and software level but Silicon Valley had and has very smart engineers, it was the two of them that were needed to make the magic happen.
