Just finished Promised Neverland Season 2 recently and I thought the season and especially the ending was very weak. Is it worth reading the manga or should I just move along?
I've finished a little over half the manga and I would say skip it. The series peaked on its first arc, everything after that is a total waste of time.
I disagree completely. Read the manga from where the first season ended. They skipped over multiple arcs (one of them being a fan favorite) at first and then completely derailed the story for the second half of season 2.
