Aldrich Killian is a great villain, but he's just that, a villain! a secondary character...not the whirlwind of a character that people expected, not the Marvel version of Heath's Joker fans have been clamouring for, and that's fine because it was never meant to be like that. I find it funny that a lot of people seem to really be missing how much of a Tony centric film this is, everything from the fights to the quips to the secondary characters all tells a story about who Tony stark was and is. Killian being the mandarin only serves to provide people with a more practical and naturalistic version of the character and someone who's arc in the film tells us a lot about Tony and his past mistakes coming back to haunt him.
The Ben Kingsley stuff is just a statement from Killian (and Black) at how people find it easy to villify someone that looks and acts like that. Which could be seen as a statement on the mandarin himself. Either way it creates a pretty compelling story all over, rather than the same predictable stuff.
How is that half assing it in anyway, the only thing Black is guilty of is misdirecting people, not dropping the ball
