Season 1 was really good, and while I saw a need for the social engineering/character backstories aspects, they could've still had the other two seasons incorporate more hacking as in S1.
I am a huge fan of Mr. Robot and I highly recommend anyone who hasn't seen it to give it a try. Season 01 is great but I do warn you that season 02 can feel slow as its helping build up for season 03. But the payoff is definitely worth it. It is however one of those shows you have to actively watch instead of other shows such as the Office where you just turn it on and kinda do other things as you watch.
