I usually don't write reviews, but I'm making a special exception for The Final Act.
One word description: INCREDIBLE! To me it felt like it was on an entirely different level than the first season. No fillers, much more emotion(I cried on a few episodes!), the art was greatly improved, a lot more character development with Sesshomaru(My favorite character), I could go on and on.
I just can't say enough how thoroughly impressed I was with this season! If you like Inuyasha, even just a little bit, you will not be disappointed with The Final Act. I will probably rewatch it again in a couple months.
