There's no other manga like this monthly that I would eagerly wait with excitement and intrigue, where the gore parts were necessary and not just a sick display (because some authors enjoy seeing guts flying and try to justify it), where the action was unique (come on, they designed a whole new equipment just to fight the titans!) the story was managed fairly well and kept me excited to the very end and the only low part for me was the politic arc without titans (that was directed better in the anime).
I think Marley had to be destroyed honestly, the culture they had was just too sick, Eren knew they had no peaceful way to solve their differences, one of them had to fall ... I'm glad the site that trained kids to die (and that they thought of them as less than trash) in the name of the nation's interest in expanding and destroying other nations using the power of the people they claim to hate was the one obliterated... I'm not glad that innocent people died in the process, just talking about that nation and their culture of terror and slavery.
Also please let Reiner fucking die already
