@tking22 - Haven't seen the Kenshin movie, but have heard great things of it. Also on the subject of Assassination Classroom, the actor playing Ed was also in AC.
In general if the characters are of the nationality of your talent pool then yeah, we're going to get a decent adaptation. It's when they take place in other regions that it get <insert colour> washed. Just an issue with the industry in general.
So here's to hoping that the yellowing of the cast is FMA's only flaw.
Also sorry about the non-quoting, for some reason the forum is not letting me quote or use cut/paste.
