As an Engineer and manga enthusiast, I personally have to say that Dr. Stone really sets up the bar high for the Edutainment genre. It is very difficult to develop the science concepts the author uses but Dr. Stone does that beautifully, and it also explains that Science is not just knowing stuff but a series of continuous trials and errors until you meet your goal.
The characters are also a great part of the story; many of them are relatable and they all have some sort of uniqueness but they don't try to stand out. They all have a role and they play it perfectly.
I really recommend this series for all science enthusiasts, it is a great manga that deserves to be read.
