That isn't to say the experience or the work was bad. Just that it's definitely not for everyone. Personally, I feel like a lot of people probably stumbled across a chapter, decided to start reading, but dropped it realtively quickly due to a certain amount of stuff you just have to accept while reading.
And that most likely stems from this webtoon tying into several others by the same author. "Planetary Human" came to be as a prequel to "Tidal Territory" after the second season of that webseries left the author dissatisfied. It does have its own sequel as well, which is still ongoing, alongside several stories that loosely belong to the same universe too. Confusing? Sure is.
Imo, you can either read "Planetary Human" as a standalone and be a little confused here and there about recurring characters that most translators thankfully point out are from another work. Or you try tackling the entire universe starting with this webtoon right here.

Story:
Tbh, it isn't bad. It's simply messy. Jo Seok himself laments this in the afterword. You can find some fun ideas in here. The concept is interesting, especially since it differs for everyone affected. There's even some nice twists. What might dicourage people from finishing the story is its pacing.
Sometimes, you don't have enough time with newly occuring stuff, but the plot already moves forward. I had to go back at times to re-read a chapter. Chapter 97 felt like a good enough ending to me which made me confused about the last chapter - 98. I guess it makes more sense if you know that it's supposed to be a transition to "Tidal Territory".

Art:
Still okay-ish. Nothing too fancy. Some effects looked cool though.

Tl;dr:
If you're willing to accept the weirdest things to a certain extent, and go for a ride into some bizarre stuff that ranges from interesting to wtf - go for it. Spend a few afternoons scrolling through the chapters.
If you're not the type for unpolished storytelling where the author just has fun drawing but sometimes loses sight of the reader - yeah, probably not for you.
