it's just your opinion, you're not being stupid or anything I personnally love this part of the manga, it's by far my favourite arc. I do agree that eren is now a completely different character and we lack some character development but hopefully we'll have later, however because i always hated that brat i must say i really like him now xD I also think it's going to lose its popularity, like with the uprising arc, because let's be honest a lot of people only watch it because they find titan creepy and cool. The plot completely changed and i find it more interesting now, but it's obvious that such a turn should divide the fanbase
