The original Digimon series started with seven kids who knew each other from summer camp. They had a past event in common to unite them. They had the time to explore the Digital World without constantly being attacked and rushed through digivolutions. They learned and grew over time like real people. New digivolutions mattered more since they didn't come as quickly. You had the time to know the children and Digimon. There were good to evil Digimon everywhere instead of just good or evil Digimon. This new show recycles and rushes through everything while doing it worse.
