Japanese phonetic spelling. Same reason the japanese original title for Battle Royale is "Batoru rowaiaru" and Audition's is "Ôdishon" to name a couple that pop to mind.
You are totally mad, man? Omg... Can't believe in your words... It's one of the best 2010 movies... So dramatic movie... I even almost burst in tears... How this movie can't bother you ??
Acting and setting are great, everything else.. give me a break. Pathethic, absurd (are we suppose to acknowledge the fact that this would ever be accepted?)
And.. SPOILERS (but really, you're better off not watching it)
Why the f*ck did they never run away? They had cars, they could roam freely etc, the only thing their survival instinct tells them is to and try prove their love to some people, really? Not step on the gas pedal and go to the end of the world? Pfff. And they willingly accept the fact that their donors, jesus christ. This idea had potential but it should've been done much much better.
Don't go there.. i see the 'point', yes the final message is touching and all, but they've should've done better with the basic idea, explain a bit more so i could at least imagine that it's a possible situation.
You're not getting it. The point, and the tragedy of the film/book (you should read the book, btw), is that these people have been conditioned as a class, over generations, not to question their fate.
Perhaps it comes across better in the book than the movie, but I can't really separate them since I read the book first. That said, a lot of people had the same complaints about the book as you had about the movie. My only real complaint about the movie is that it focused too much on a contrived love triangle at the expense of some of the more subtle character-building from the book.
edit: from a very good review by M. John Harrison (of the book):
And I'd point out that it's also about how the rest of the society depicted in the book has conditioned themselves so well to believe that the clones AREN'T people that they had to have a special experimental school to test whether they have SOULS. There's a lot going on in this book/movie, and you really do have to fight your initial urge to yell at these people, or at least re-channel that energy into trying to understand what Ishiguro is doing.
