On one hand it's hard to say a highly-rated, Golden Globe winning TV series like Mr Robot is unappreciated, but if my introduction and prior opinion of the show is any indication of how percieve the show, I think it may often be overlooked by technology enthusiasts like myself.
I know that personally I never really gave the show a chance, or even bothered to look at the ratings, because I was sure it was simply bound to be another failed attempt to bring coding and hacking to the mainstream in a entertaining manner, which usually just leads to cringe worthy scenes like this, this, this, etc -- excuse me while I go vomit real quick -- but this is not the case with Mr Robot. The show incorporates a lot of real technologies and methods while managing to be entertaining. Some stuff is dummed down a bit as to be expected, but not so as to be unbelievable or cheesy. I've heard that the creators also took some community notes into consideration and improved the accuracy even more in season 2.
All in all, it's a great show so far and I really recommend it.
