I agree on that it was good for the most part. If I hadn't read the Jinchuu Arc in the Manga, I would have probably thought it was amazing. But many important parts were left out, just as Kaoru's supposed "death" and Kenshin's complete breakdown, the meeting with Tomoe's father... and much more. I was kinda missing it. But if I leave that behind, I can easily say that I loved the second OVA.
It wasn't like the Manga/Anime at all, and I missed the little "Oro" moments and happy faces, but I think that what they did fit very with the dark atmosphere.
I was very happy with the 15 years later "arc", certainly with the return of Sano, and the appearance of Kenji. ^_^ I would have wished for a better ending, of course, but I have to say that I thought the ending was truely beautiful. Simple, yet beautiful. Kenshin's homecoming reminded me of Kenshin's homecoming after the Kyoto arc.
The best part of the ova(s) is the music though. 8D Along with the Tsuiokuhen OST, the Seisouhen OST holds some of my favourite music.
Nothing beats Tsuiokuhen. :3
