This show is pretentious and childish
TLDR: Mr Robot is a below average in my opinion, but definitely not terrible.
I watched all three seasons of mr robot some time ago and I was pretty disappointed. Lemme explain.
The Cinematography is one of the best I've ever seen. Sam Esmail is a great director.
The Script is one of the worst I've ever seen Sam Esmail is a bad writer.
The same problem a show like game of thrones season 7/8 have. No matter how great it looks, if the script sucks, the show/season sucks. Though mr robot maybe isn't as bad as game of thrones, you get the point.
__The Dialogue:__The show feels like a r/im14andthisisdeep comic with a 30 million budget. The dialogue is so cheesy with all the unironic "we live in a society" stuff that is so cheesy and stupid, sometimes i just laugh up by a speech that's meant to be super serious. Though I give credit where credit is due, most dialogue that isn't from elliot or his sister is pretty good, with the exceptions of times where they speak complete gibberish just to not spoil the audience about what's gonna happen in the next season (best example is Philipp talking with Angela in the end of S3 and telling her that whatever whiterose is doing is a lie. (Rewatch it and you'll immediately realize it).
The Plot: One word: Confusing. The entire story up at this point was nothing but confusing and you have all the time no idea what the fuck is going on. Ralph himself complained by his star wars VII review that it didn't explained much and mr robot is a radical example of that: literally everything stays unanswered for most of the time. Half of season 2 you have no idea where the hell the main character is and a plot twist from season 1 (elliots blackout and the car he wakes up in) has still not been explained at all. You only find out who knocked on elliots door in the end of s1 around 4/5 hours later.
Besides that, the rest just feels like a 14 year old wrote it:
the evil 1% is taking over the world, and society is bad. The hacker group rebels must fight them!
Reminds me of these underground rebel friend groups in kids movies which the main protagonist joins (like the emoji movie).
The plot is also barely moving forward for most of the time. Think about it: what big happened in these three seasons? Characters just talk about the same problems over and over again with no real conclusion. I bet you could have cut these 3 seasons down to 2 if not even a single season and it would still make perfectly sense. It's not that it's a slow pacing, its that it's not moving forward at all many times. This creates boredom and one of the reason the viewerbase literally split in half when season 2 came out (from a million to 500k).
Also lets not talk about how laughably the idea is that millions of people are immediately rioting and starting a socialist revolution once a big company loses some security.
characters: Elliot is not a character, he is a caricature. Best explained by either the Doomer (look it up) or the Virgin from the Virgin vs Chad memes: a millennial who lives alone, always wears a black hoodie, depressed, always on drugs, "we live in a society", and hates "the system". Elliot is no character. He is literally a joke made by 4chan about such depressed millennials: doomers. Only differences are that he can hack, hasn't lost a girlfriend (at least for s1) and that he sees his dead father. I mean, would you take a character serious that is the real version of Chad from Virgin vs Chad, with all the character tropes? No you wouldn't.
I remember ralph saying that every character has a clearly set goal which is just bullshit. Most of the time you have 0 clue what the motivation for each character is. An example is Tyrell, don't tell me you ever understood why he did anything that he did. Same counts for Elliot too. In the end of s1 he accepted mr robot. Same day in court he betrays him.
Another thing I hate is the two dimensionality of characters. You're either a poor depressed doomer hacker who hates society and capitalism or a power hungry quintillionaire who has his own private owned continent. Obviously every rich person is portrayed as evil and all poor as good too but that's my next point.
politics (boy get ready for some controversy): This is the most pandering show I've ever seen. It's like sam screams at the screen "Hillary won the popular vote!". In writing when you don't present the factions objectively but explicitly show the one side as evil baddies (capitalists) and the other as good and full of nice guys (socialists), it's called a punching bag. E corp is a punching bag. (the closer look made a great video on it.
The only way you can really enjoy the mr robot world is when you think of it as an alternative universe where the amount of money you have represents how much political power you have. In addition the entire world is corporatist (when a government and a select few monopolies work together to control the entire economy together, making it impossible for people to start their own businesses).
It is hard to imagine mr robot in our world, because our world has none of that. But then again the show never stops to pretend that our world is exactly like that, especially when they mention trump.
Thinking about it, i bet i also have much more points to say but I'm writing already for an hour, so i can tell more about my opinion in the replies.
