I love this show!!! I just watched all the episodes and the movies! Totally got hooked.
I do agree with Wolfen, that the story kind of drags on, I wish they showed more Kagome and InuYasha love connection, but there never was, built up to nothing, they didn't even destroy Nuraku, and Muroku and Sango didn't even get together.

Nothing really was really fixed. But my love for the characters was what kept me going.
I there there was a lot of character development though, I disagree with what you said.
