Hell even on Rotten tomatoes, it is now rated as "rotten" after the critic reviews have come in. So it seems critics also hated it.
No, they didn't "hate" it. The problem with RT reducing critic reviews to a yes-no binary is that it bulldozes over nuance -- anything in the middle ground has to be arbitrarily reduced to one of the two extremes, which makes it effectively useless. It also gives "Rotten" ratings to anything below 60% -- the show is currently at 59% as of this writing, which means that the majority of critics gave it positive reviews. It's bizarre to call that "Rotten." Just a one-percent improvement would flip it to "Fresh." Which underlines how silly it is to reduce nuanced things to binaries.
Despite how people tend to treat them, the numbers on aggregate sites are only meant to be a crude first-glance overview, not the end goal of the process. You're supposed to actually read the reviews to get a more detailed understanding. And from skimming over the reviews, it seems that most of the so-called "negative" reviews are actually more ambivalent, seeing both good and bad things in the show.
Also, audience ratings are currently at 75%, which is quite good. Because the critic and audience ratings are calculated differently, it's not statistically valid to compare them, another reason the site is badly designed. The critic ratings usually tend to come out lower than the audience ratings, but if you actually make the effort to read the reviews, you often find that the critic and audience reviews are in general agreement about the strengths and weaknesses of the show, even when the numbers artificially suggest a wide difference of opinion.
Also, the critic ratings are based on a mere 56 reviews, while the audience ratings are based on more than a thousand. So statistically speaking, the audience rating is more trustworthy because it's based on a larger sample, even aside from the inherent flaws in the way the critic results are presented. It's quite possible the critic score will shift considerably as more reviews come in.
As for Reddit, YouTube, and the like, those can't be taken seriously. There are plenty of people who go out of their way to post negative, angry reviews because it generates attention. It's self-serving and dishonest and has no bearing on the actual merit of a show or film.
