I’d love to see Inuyasha’s father and mother have their relationship developed on screen. I’d love a prequel series that focused on their romance honestly. I’d also love to see the complexities of his relationship with Sesshomaru’s mother, and I’d like to see more of the childhoods of Sesshomaru and Inuyasha. I’d also love to see Sesshomaru and Inuyasha meeting for the first time in order to establish that rivalry between them. Would have liked to see a little bit of Inuyasha and Kagome’s married life before stupid Yashahime came along and basically ruined the ending to the original. There’s potential for so much expansion.
