I can understand Killian didn't have the rings or the look of the classic Mandarin, and this lack iconography burns many fans. But, I think the spirit of the character worked in many ways.
Kinglsey represents the look and iconography of the mandarin while Pearce is his spirit,at least that's the way I see it.
