Things are moving at a breakneck speed, but to be honest with how the last arcs have dragged on I'm glad for it. Ever since the goal became to go from this stone world to visiting the moon there's been this constant worry of how exactly the manga will depict that process without being boring or too long. This seems like a good solution. We skim over the production and can hopefully focus on the final confrontation and then wrap it all up in a nice package.
Looking back I'm not quite sure what to think of Dr. Stone. it's been a very interesting manga, had a good start but once it started putting the progression of science over character development I lost interest and it hasn't managed to regain that spark it had in the beginning. At the same time I'm happy we're getting this story that's all about celebrating science and human accomplishments. Maybe a bit simplified and zappy, but kids today deserve some of those messages. There's so many bad things out there it's easy to forget many of the amazing things humanity have done.
