Painted Skin 2: He has decent chemistry with Jet Li and Zhao Wei, but that's only because they have chemistry with everyone. The camera angles in that scene confused me until I realized they were doing it in hopes we wouldn't notice the lack of chemistry.
Taichi: Yeah, about 95% of his drama and trauma was when he was 5.
Wu Dang: Definitely. Initially a I was "I'd rather they not pair them, just because of the age thing, not that there'd be anything actually wrong with it" and later I was "they have pretty much paired them and seem relieved to have it out of the way."
