It's worth the viewing struggle and discomfort of 1-4 to land on the feature length episode 5 of Expats. The series works best when it tackles the real world social/class struggles in Hong Kong with stellar acting from two main characters.   Domestic help workers to the very rich,  Puri ( Amelyn Pardenilla ) + Olivia ( Flora Chan ) , along with the supporting cast, truly steal this show.
