After reading deeper and deeper into the manga, I realized that the Hueco Mundo Story Arc is 99% the same as the Soul Society Arc. Here are just some similarities I realized:
*Going to save the Girl
*Everyone notices Sado's spiritual force drop/ Sado almost dies
*Sado's last attack to Captain/Espada might have taken the enemy out
*A weak ally turns out to be a strong one with big.. assets? Nell and Yoruichi
*Technical Enemy can regenerate
*Fighting of unimportant enemies (3 digited Arrancar/ Seated Officers)
*Lazy, most likely strong Captain/Espada
There is much more..
My question: Do you think this is a remake of the Soul Society Arc?
Also, are there any big ones that i missed?
