I like Casshern, I really do. But around my area it seems like I'm the only one who's ever heard of this series. I'll give a very brief rundown of the origin of this franchise:
Shinzo Ningen Kyashan, or translated as Neo-Human Casshan, was an anime series created by animation studio Tatsunoko Productions in 1973. This series was never localized since the Japanese super-hero genre was never really that popular here in America. Years later in 2003, the OVA (titled "Robot Hunter Casshan") was subtitled and released on two DVDs (both of which you can find here on Amazon, at the time of this review of course). In 2007, the live-action version was re-cut, subtitled and officially released by Dreamworks here in America, titled "Casshern." In early 2010, Casshan made an appearance as a playable character in the fighting game "Tatsunoko Vs. Capcom" for the Nintendo Wii. I'm really not sure what's going on with the translation of this character's name; they just can't seem to decide which one to use. But anyway, just know that "Casshan" and "Casshern" are the same character.
Now it's mid-2010 (again, at time of this review), and here we have Casshern Sins. Suffice it to say, FUNimation did a fantastic job of localizing this great anime. If you've never seen it before, you don't need to know any of Casshern's back-story to get into it, but I think it's a lot more fulfilling if you do watch the other Casshern material. I won't go into the story, since that would make this review more lengthy than it already is and that's something you can probably find anywhere on the internet, but rest assured that it's one you won't soon forget. All of the English voice actors sound nearly identical to their Japanese counterparts. There are a few misses if you compare it to the Japanese version, but these differences are negligible. The script was also well translated, and I feel it isn't watered down for U.S. audiences, which can be the case for some translated animes. Also, from what I've noticed, no violence, language or any scenes were cut out from the original, which is greatly appreciated for any kind of fan for anime.
*IN SHORT: If you are a fan of Casshern, or have seen the original Japanese version of this anime, this is well worth the investment. If you've never heard of this franchise or anime, you owe it to yourself to pick this up and experience a story you won't soon forget.
