It's just the usual pacing of Shonen Jump mangas. Theyre meant to be face-paced and have a sense of urgency cuz it's one chapter per week release. You can feel the same pacing with Demon Slayer, JJK, Sakamoto Days, SpyxFamily etc. cuz they all came from Shonen Jump. They tend to get straight to the point in each panel cuz they have a limited number of pages to complete before the deadline. It's quite surprising Dr. Stone was a weekly release given how detailed the drawings are. JJK, for example, had a time where the author released half assed drawings just to meet the deadline despite having injuries on his hand.

By the latest chapter, it all just feels like an overthought feverdream . The pacing in the manga feels more jaunted and faster than the anime even tho the anime also felt like it started getting fast. Or maybe the manga was jaunted from the start and the anime happens to make it feel more full-boddied than the manga bc anime generally requires more flow. Like compared to the first season and stuff, the journey around the world ended up very shorthanded for even what I expected. There was so much potential in making it slightly less rushed but still was enjoyable. Just rushed as it went to the world journey and rocket and negotiating on the moon. It felt anticlimactic that it was just a rando colony of tiny sentient machines. Idk how to feel about it. It would be worth it if we eventually get to see the time machine actually work, but would the author bother to go that far when it seems like they already decided to rush the ending? Since a certain point, the whole plot just started feeling like they were vasically telling me the whole story in the fork of bullet points as if it was the outline instead of a final draft of a novel ╮( ̄▽ ̄)╭. Fun story tho truly. All that's left is Senku and kohaku's wedding post-time machine achievement and (by a miracle) Ryusui turning in curiosity to Xeno and Stanley with a look of "I saw something" and them being like "so we been engaged since a day before the suicidal rocket launch but who needs a ceremony (● ̄(エ) ̄●)" . Everyone, esp chrome (except for Senku and Ryusui who were there when Stanley was depetrified and IMMEDIATELY caressed Xeno's lips) being like
