Speed Racer- This film really did it for me because it is so Anime. Everything from the colored hair, the futuristic setting, the fast paced storyline and the over the top action scenes is in Speed Racer and the film manages to stay true to the original show while paying tribute to the Anime culture.
Casshern- Although Casshern does feature a bunch of Anime science fiction cliches it doesn´t matter because we´ve never seen it in live action, so it feels fresh. Just like Speed Racer Casshern is a true live action Anime.
It´s too bad these films recieved bad to mixed reviews because that just shows that live action Anime will never be appreciated and big movie companies were probably stop producing them. Hopefully Battle Angel will save the genre from dying so quickly.
