I mean, with so much media in the world, yeah, expectations are higher, but Nanatsu no Taizai was good and then had a slow decline to what it is now, it just seems like Nakaba didn't exactly know what he wanted to do for a long while, a lot of the 10 commandments didn't really get good fights or payoffs, it was either a stomp for them or their opponent, we never got one of those equal fights that I like in manga, and a lot of the sins were made too weak for too long, Ban, Diane, King, Gowther, and even Merlin kind've didn't get to do a lot in the commandment arcs, Escanor and Meliodas kinda stole the show for a very long time, the Mael stuff was cool, but I felt it had some issues, when Zeldris FINALLY got his moment to shine, it looked like we were finally gonna get some greatness and we did, and then when the Original Demon showed up... everything went down hill from there
I just felt that there were no stakes for a long time, very little characters died or were in danger, I guess Escnaor counted, but once again, I felt like he didn't even need to be there, point being, the series got lazy and boring
Speaking of Gowther, is it just me, or has he not had a line of dialogue or anything important to do for an extremely long time, like I kinda forgot he existed
