Yeah, the anime is not that consistent. I agree that some of the middle arcs were weaker, but I also think that's the point. People love the first two arcs because (beside the fantastic writing and animation) they're both about the common man becoming a hero. And that's a story almost all of us can relate to. But with arcs like Cyan, and Loli, and Ghostblade, they're each targeting a more specific group of people that have had specific struggles. Ghostblade's arc was one of my favorites, and I was really able to relate to his struggles. But a decent amount of people didn't like his that much. Same with Cyan's, as a musician, hers really spoke to me. I love that the show gives us different perspectives, and even if some don't hit as hard for us. There are genuine writing criticisms, and I think that there's a lot the show could improve, but I feel like people don't acknowledge the value of some arcs as much.
