Anyone that didn't realize the writing was gonna be dogshit the instant it was revealed that the main character is a lesbian has the pattern recognition of a gnat.
"why did it take two hours to figure out what was up with that weird rock? I had to watch a spaceship dock for like ten minutes to classical music, what was the point? Finally the AI seemed like it was moving the plot, but then there was a five minute light show before some weird aging sequence and then dude turned into a space baby without telling me exactly what happened. 0/10 overrated garbage that I regret slogging through even on 2x speed."
This but unironically. Sci fi has 2 selling points, exploring scientifically fantastical scenarios in obscene detail, or exploring characters existing and navigate within these scenarios. Pluribus doesn't bother exploring the hive anymore than the average stellaris civic description does. In fact arguably stellaris civic descriptions explore it in more depth, so it already fails at point 1.
And as for point two, Carol is a retard that is incapable of asking any of the right questions that make explring these scenarios intresting.
Other people in the thread already explained this with examples:
Show me people eating each other. Show me the hive mind mass-suiciding the ill and infirm by starvation. Show me the utter chaos caused by doing dumb shit like letting all the zoo animals (and presumably farm animals) free. Show me a fucking alien saucer hovering above the white house with a bunch of little green men laughing about how soon they'll own the earth. Ask some moral questions, actually ASK the questions don't just allude to them. Have Carol straight up tell the hivemind to its face that it murdered billions of people by taking over their minds and effectively wiping their brains clean and get hysterical when it tries to gaslight her otherwise. Have the hivemind say some wild shit like "free will is like an addiction to crystal meth and we had to detox you" because it's a weird alien intelligence (even if it's made of humans) and its morals don't make sense from a human perspective. Approach the idea that maybe the hivemind is also a sort of afterlife if it can back up the knowledge of everyone in it. Ask if the hivemind can "pretend" to be individuals, or if it can even comprehend the concept of individuality, or if it can maybe link everyone without nuking their free will. Do SOMETHING besides wasting my time with melodrama that I could get from any show on TV.
There's a million things you can do with scifi, shitty lesbian melodrama isn't one of them. You can slowburn characters or you can slowburn plot, with the implication of course that either one will eventually catch up, but you can't slowburn both with no promise of payoff.
Pluribus in this regard remidns me of the last man on earth:
A show with a somewhat similar premise, Virus wipes out humanity except a group of people immune and we follow the immune. The difference being that it set itself up as a melodrama from the very get go. There's no DNA alien viruses or any of that shit, you know what you're in for. Ironically it actually explores point 2 a lot better because most of it is in fact about how people naturally react to the sitiuation and what they go through to survive and does melodrama way better despite being a comedy.
Pluribus for the most part is a self indulgent art project using sci fi as a vineer made by a director that bought into his own hype and surrounded himself by yes men that are too afraid to tell him no because "Well he's a genious, he must know what he's doing even if it seems like raw dogshit to us mere mortals." much the same way lucas did with the prequels.
Case in point, episode two's intro being 10 minute long nothingburger of the woman going to the plane. There's slow, and then there's taking the piss.
Vince copied the "Long dramatic slow establishing scene" from BB and BCS somehow without understanding why those scenes worked in that specific context of decompressing the plot and creating a sense of either mystery or urgency as to what is going to happen or wondering how it happened, so he just slapped it on episode 2 because that's what a show by vince is supposed to do/look like.
Its like you told an AI to copy his style and this is what it shat out not understanding why. The entire show is self indulgent as fuck and reaks of a director surrounded by yesmen.
