I've only recently gotten into Anime and Manga. So far, the anime I've seen, my only complaint is how easy it is to write a script for Inuyasha. Per episode, have somebody yell "Inuyasha" 20 to 30 times, while you have Inuyasha yell "Kagome" 5-8 times. Anything else is filler. ???
I've been getting into the manga recently, though, and I'm surprised how well the character development is I just finished the prequel to Tokyo Ghoul, and the groundwork was laid well. Started reading and watching Death Note, and, well, I'm binging on it all. LOL.
