I agree that the second season of Psycho-Pass has more ridiculous schlock, but I personally don't think that makes it better. While you might call it intellectual bullshit I think most people who enjoyed Psycho-Pass thought it's ideas were at the very least interesting. It was because the second season misunderstood those themes so badly that most of us don't like it as much.

You are correct in your assertion that Sybil seems to abjectly ineffective and immoral (to be fair we're seeing the system through the eyes of those people whose job it is to fix it's faults, if the show followed plumbers you would think the world would have plumbing issues), but that's what makes the first season so powerful. Instead of the heroes trying to bring down the government they realize that doing so would cause more harm then good, and have to begrudgingly accept the status quo. Sybil doesn't seem to be trying to make a perfect world, it is just trying to assert its will and keep its position of power. That's why it's using horribly ineffective weapons like dominators and ephemeral measures of sanity criminal coefficients, to maintain control through fear.

As to Makishima, it's well established that he is one of a small number of people who are criminally asymptomatic, in other words psychopaths. Psychopaths in the real world tend to be high performing and charismatic, while you're correct that the fact he possesses so many other talents seems unlikely, I didn't think it was ever taken to unbelievable extremes. I thought his back story made his motivations clear enough, and those motivations seemed sufficient to lead him to acquire the skills he did. Personally I didn't need to see a scene with him escaping to Indonesia to learn Pencak Silat.

As far as the other villains are concerned, it's true that a lot of them are motivated by insanity, but it's clearly explained to be a function of the stress the society such a messed up society creates. Even in today's society the mentally ill often don't get the treatment they need because of the social stigma associated with it, Psycho-Pass illustrates how much worse the problem could be.

I agree that most of the rest of the cast have their characters built upon archetypes (which is true of nearly all fiction), but I think you aren't giving enough credit to Ginoza, Akane or Kogami. They all develop over the course of the show, and a given more depth as their insecurities are revealed.

I agree that some of the exposition comes across as awkward, but it seems pretty clear that Akane is being treated as more ignorant than she is to her chagrin (in the very first episode she complains that she wrote her thesis about the contagious nature of stress). I think those conversations also establish the sense that the other characters don't trust Akane's formal education.

The use of quotation can make both characters and writers come across as pretentious, however personally I thought that given the ideas they were discussing the quotes seemed relevant. I agree that paraphrasing might have come across as less intellectually elitist, because seriously, who actually memorizes quotes. Ultimately I think it's clear that Psycho-Pass acknowledged that it wasn't created in a vacuum and wanted to explicitly respond to the ideas of other fiction, without plagiarizing them.

I don't mean to say that you're wrong for not enjoying the same things as most of us (that's taste for you), but I do feel a lot of what you said is misguided.
