First thing I gotta say is even though I haven't read the manga I was very impressed. As always, there's probably more plot detail in the manga but you can still follow this action packed plot very well. Ratings are good and the sequels alone should tell you it's worth the watch. If you're a Japanese history fan or even a weapons fan in general, you'll enjoy the samurai/new age theme. I especially loved Sagara. He brought the fresh and fun humor and reminds me a bit of Kenpachi from the Bleach series lol Anyway, I was worried about an adaptation but this movie was great! Honestly, I think as long as adaptations don't get white-washed they're usually pretty good lol Enjoy...
