Mr. Robot should have ended at S1 because S2 is a complete u-turn. The show is no longer targeted at the general viewer but viewers that have a high tolerance for the shows ridiculously slow story progression, theory enthusiasts, and viewers that love 'emotional development' (by that I mean the ever-so frequent 5 minute long stares characters like Angela are seen doing).
Season 2 overall is not a season for the average viewer. From the get go you will notice the massive (and negative) change from S1 to S2 in terms of the exaggerated cinematography, extreme lack of story progression, and misuse of emotional development as mentioned above. You will find yourself painfully forcing your way through the first 5 episodes for the story-line to actually begin, and by the end of the season you will ask yourself -- "did I really just put myself through those painful episodes for that?".
Ultimately, I will not be watching this show on a week-to-week basis as I have done since season 1. With that said, I feel absolutely no excitement to watch season 3. And I will most likely stop watching it completely if they continue with this new approach.
Fix up. Your rating is going down for a reason.
