Is The Golden Child not as well received as Eddie Murphy's other '80s movies because he didn't have a great foil?
What I mean is that in 48 HRs., he had Nick Nolte, in Trading Places, he had Dan Aykroyd, in Beverly Hills Cop, he had John Ashton and Judge Reinhold, and in Coming to America, he had Arsenio Hall to play off of.
In The Golden Child, Eddie Murphy doesn't seem to have a partner that could immediately bring the best out of him as well as hold their own. I guess here, it's supposed to be Charlotte Lewis, but she despite her gentle yet exotic beauty, is hopelessly wooden and lacking in charisma and chemistry with Murphy. And I'm hesitant to suggest that Charles Dance's villain character is that needed foil/"partner in crime" that I alluded to.
This is also likely why Best Defense in part didn't work, because Eddie Murphy shouldn't be forced to due all of the heavy lifting so to speak by himself.
