Most of the media I have seen that showcase a romantic relationship between a homosexual couple portray in a stereotypical way.
For example the show Modern Family, which is groundbreaking in that it features a homosexual couple as one of the families, portrays the couple stereotypically sometimes. For example, one of the partners enjoys dressing his daughter up as divas.
What I found very refreshing about the Hong Kong movie “Happy Together” (1997) is that the relationship of the homosexual couple lacks any stereotypical elements. In addition, the fact the couple is homosexual it not important in the plot.
