Based on what I saw and based on my memory (which might not be 100% correct, but if you need the details I can suffer and watch the first couple of episodes again
This show is known for its "science". Unfortunately, instead of science I saw a guy who fought with lions barehanded. And people resurrected after hundreds (thousands?) of years after being petrified or whatever it was (does the author know?
Also a lot of "science" there seems to be just bullshit. So this show (because it is advertised as containing some science) actually promotes pseudo-science. People watching this show probably feel smart, but they're just misguided.
Characters are very poorly constructed. They don't feel real. Instead they feel more like tokens to act as specific roles. They don't need names. They can be called: "the brain", "the muscles" etc.
The "romance" couldn't be more schematic. The girl seemed to be retarded or something (and the boy was not much better).
The main character is presented as if he knows all branches of science, but he actually doesn't know too much. As far as I remember, even the scientific method and the process of scientific discovery is not done right, not only the details of particular sciences.
In this season we have Ascendance of a Bookworm. Science, crafts and technology there are mostly legit (despite it being a fantasy isekai). The girl is weak, she doesn't know everything. But she knows ENOUGH, and that makes a difference. Ascendance of a Bookworm is much closer to what Dr Stone should be as far as the scientific part is concerned. Have you seen when she attempted to make pseudo-papyrus and how she failed? Yes, she FAILED at that, because it required too much time and work, which is true. She didn't have tools, she tried to do it fully manually. Instead as far as Dr Stone is concerned, we got pseudo-scientific gibberish and a pretty bad shounen.
