I'm straight up never going to see this movie. As KB said, anime should not be remade for white people. I would extend that to say that foreign movies generally should not be remade for the american public. The Girl With the Dragon Tattoo? Awesome original movie, totally watchable with subtitles. English remake featuring Daniel Craig? Fucking AWFUL. The biggest problem, in my opinion, is that remade movies always, always play to the lowest audience denominator. They remove context, storyline and subtext in an effort to make the movie appealing to the most people as possible. It's a cash grab. edit: I mean straight up there are tons of asian actors who could do this role incredibly well, especially if you include korean and chinese actors and not just Japanese. I mean, Doona Bae from Sense8 would KILL this role.
Didn't even know there was an American remake. Guess that's one I won't be watching based off the collective thesis on remade foreign films anyways. I'd like to think the twisted version of plot lines to an "American" audience follows suit that an American actor(ress) would be the type fit for the job. In an ideal situation with a well-made reproduction of the movie in live action, then the actor or actress fitting of the original film's background would be the star. At least, that's the hope for the hypothetical expectation... Sidenote: Did you finish Sense8 and would you recommend it?
I did finish Sense8. I liked it - It's good as long as you're not expecting shakespeare. Just remember it's sci fi from the people who made the Matrix, so it tries to be more profound than it really is.
