You are right, the only difference is that snk was pretty dark from the beginning and I don't think jjk will reach the darkness and despair that we currently see in snk, but it's still a very serious and mature story. Yuji is pretty similar to Eren and by some details we saw in the previous chapters, I think his family/dad will have a big role in the future. Unfortunately I think the next chapters will be absolutely miserable for Yuji.
True. And oh i forgot to clarify that it was never my intention to actually compare these two stories. I pointed all that out because i read a lot of comments saying "he's like eren. He's like eren" or prior to that people comparing Yuuji to Midoriya. So i wanted to add why i do agree they're similar. Yuuji and Eren that is, not Midoriya at all. But in no case they're the same. They're completely different stories with dark elements that can be seen in any other story. They just have similarities but they should never be read as if they're the same.
Yeah, I think snk and jjk have some themes in common. Itadori and Eren are similar, I think that if Eren had lived in a normal world probably he'd be very close to Itadori's personality. Midoriya is another type of character, I agree with you.
I've been saying this since Yuuji first died. He's probably the character who most resembles Eren. Not only because he got his power due to something he ate, but because the maturity of Jujutsu Kaisen is closer to that of attack on titan. Let's remember that this manga is been out for only 2 years or so. Attack on titan has been around for more than 7 years. So, jujutsu kaisen will probably reach deeper subjects and turn into a darker manga each passing chapter. Which i personally like a lot. This is nothing like my hero academia like some people compared to in the beginning. Megumi himself has specified also that they're not heroes. This literally means that there will be sacrifices made in order to achieve greater things. And people will die in vain no matter how much it hurts. Plus, this manga already had touched many subjects that stories with happy endings don't posses. One of them being the hopelessness that the characters will face the stronger the evil gets. Like with the colosal titan that we thought was the final boss and it turns out to be just a pawn? We are still getting started and we still don't know who will be the one actually causing the more pain to our characters.
