I am beyond surprised that Capcom actually gave Onimusha to a team that cares about the source material that they are adapting. This, in my opinion, is an amazing adaptation with superbly choreographed fight scenes and plenty of likable character moments.
The only shred of hope I had for this adaptation came from the fact that Takashi Miike was at the helm of the production as director and he is most likely the reason why action scenes look as amazing as they do. I think on its own, the show is still good, but as an adaptation of Onimusha, it is great.
Animation:
To start it off I don't think a lot of people will be fond of the CGI. I had no problem with it because the hand-drawn backgrounds looked amazing and so did all of the fights. There are so many genuinely epic shots and camera angles used here, both in and out of action sequences.
Also, the art style is just super on point, there are some areas where the color grading straight made me feel like I was watching a video of one of the games, especially when it comes to the backgrounds. If they were given a bigger budget I am sure the animation quality would've been 10/10, but it is still great imo.
Story:
The story is fairly basic, it just follows Musashi and his companions while they go on an adventure and face various foes along the way. I think many people would rather love to see an adaptation focusing on Samanosuke or Jubei, but what we have here is genuinely good and can be treated as its own "game" because it perfectly fits into the Onimusha franchise.
Character:
As I briefly mentioned earlier, the anime focuses on Musashi traveling with a bunch of other characters as they go on an adventure. All of these characters get a lot of time to shine and akin to most of the games all of these are very memorable; I would argue that the show even has some of the best characters in the series.
Conclusion:
Amazing action sequences, really likable characters, respect for the source material, & stellar choreography all make this an easy 8/10 for me and as a Capcom adaptation this is like a 9/10 lol, because they never give their IPs to people who care. I hope that this means we might be getting another Onimusha game sometimes in the future.
