well, i personally not ok about it becos
if wana intro for the first time, must intro correctly mah. there will be many chances to introduce the side stories or alternate comic plots in future for reboots.
this version of silver samurai appears in another story that they rewrote for wolverine. comics mah, they like to rewrite just like movies, like to reboot.
so fact is, there are 2 such stories or maybe 3 or 4. but since this is going to be an intro to wolverine on his history in japan, it should follow the classic first version. not the rewrites.
like spiderman movie, i m ok with the tobey maguire's version(although i am also against the organic webshooting) being that it follows the first history of spiderman. now the reboot by andrew garfield have a different take as it follows another history of spiderman. like imagine, 1st time adapt spiderman to movie, uncle ben never die at all when he become spiderman. wah i buay tahan lor.
to me I just find that comic book heroes origins must follow in their 1st adaptation. subsequent reboot anyhow i dun mind.
but of cos for movie making enjoyment sake, action wise and story is ok to me for this instalment of wolverine.
