American surnames aren't nearly the issue that un-Western friendly plots are.
Re: Vyse thinks I fail at screenplay.
American adaptation of foreign product is tricky. Too literal and you alienate casual audiences, even when using an original screenplay. Too loose and you get Dragonball Evolution. There has to be a balance between adaptation and original.
Death Note is easy. The concept doesn't rely on any prefound knowledge of Japanese culture, and it's really easy to change certain things (college entrance exams = SAT/ACT, Tokyo Music Festival = New Years Rockin Eve, etc) Same with Full Metal Panic, a license that only surprised me because of how un-PC Major Payne in a high school setting would be.
Bleach is not so easy. The core concept is based on Shintoism, unfamiliar to Americans. The sheer ungodly length of the story makes literal adaptation impossible, necessitating an original script. You would be forced to base it on the early material and introduce the inner workings of Soul Society in a sequel. You can't give arcs half-done resolutions like Soul Society. If you boiled down the whole movie to the subsitute soul reaper, the monsters he fights, and an antagonistic Quincy that wants to bring down ruin as revenge for his people, you might have a servicible two hour film. Fanboys would inevitably whine, but that always happens. I just think most of the battle would be making the premise plausible, Uryu properly introduced and evil, foreshadowing Soul Society and not making it a Japanese feudal town...and cram it into two hours without making it seem disjointed or out of place. It's doable, but it being good is another matter.
