The story starts of okay, the author seems to be holding a bit info though, he could have shared more about the world as the arcs were passing, however, on the current arc, Shibuya Incident the author starts vomiting information on you, worldbuilding, characters (their names and faces), techniques, it is just too much, it is even worst when it tries to explain how a technique works and it makes you feel even more confused. On the other hand, since the beginning of the story is too slow, the protagonist progression is too fast, we are shown a ranking where either sorcerers or curses are placed, you would expect that our protagonist would be of a low grade, technically he is, but he progressed so fast that he already feels too strong and to countermeasure this the author already made entry-level enemies too strong.
Character-wise they have okay personality, same old from the shounen genre, but I personally found their names hard to remember and their faces look the same to me, sometimes I rely on their hairstyles to know who is who, but when they say a name my mind becomes blank.
The art style is alright, crude and rough, the "sketchy" details makes the roughness of the art. As I said before, drawing the characters' faces don't seem to be the author strongest suit.
I started off enjoying this manga, but the current arc and the decision to pour too much information now for worldbuilding seems like a bad idea. It is rushed writting, thus bad writting, ideas are all over the place, too much info, some things mentioned once only to be remembered months later and the author expects us to be with the material fresh on our minds.
So compared to previous supernatural stories Shounen Jump had release, JJK is a huge let down because it has bad writing, rushed worldbuilding and indistinguishable character's art.
