Completely ruined Inuyasha for me. It should have ended in March 2010, instead they came up with a bad cash money grab sequel and ruined Sesshomaru's character by turning him into a pedophile in Episode 15. Before that, they basically teased and dangled the carrot "mystery mother" in front of us in their promotions calling it a "shocking surprise" only to reveal that it was the 7 year old child Rin; the little girl that had been travelling with him in the original series.
Rumiko basically approved Katsuyuki Sumisawa's poorly written monstrous creation, reminiscent of his distasteful satire drama CD "Asatte" which had Sesshomaru proposing to child Rin.
The new animation art in Yashahime is also horrible and ugly and the plot is boring. The characters have weird looking big ears; It's so bad that I can't unsee it. Rumiko Takahashi and Katsuyuki Sumisawa should have their careers end for creating and supporting this garbage.
