Guys I have a radical theory about Mr. Robot
Spoiler tag for the anal
Seriously, since the show is planned for multiple seasons, and we're going to find out who mr robot really is pretty soon, it's clear Mr Robot is going to move beyond FC territory.
The hackers in this show are clearly more ambitious than the anarchists in FC, who appear largely to be frustrated nihilistic young men lashing out at consumerist capitalist culture. These guys are not just going to blow up a couple buildings. They have specific grievances, they have plans, and they've shown they are capable of executing those plans (though we can question how realistic their plans are and whether they'll have the impact they hope for).
Another difference is the larger scope of this show, where we get to see the other side, the ones running the system, the "bad guys" like the exec and the CTO, the "good" accommodationists like Gideon. There are real victims, but just working stiff suffering from ennui. Also, there's even less glamorization of the hackers in this show. Elliot clearly has mental problems from the get go, and the group is portrayed as a sad bunch of people living on the margins. Even his alter ego / doppelganger is just his dad, not a charismatic gonzo guru.
What I'm trying to say is you'll enjoy this show better by not getting hung up with the similarity to FC. Remember, everything is a remix.
