While this is starting to change more and more (mostly because of fan outcry), the network’s movies are still very much mostly in a “two white folks fall in love” or a “two black folks fall in love” mode, with not many interracial romances or people of color in those romances bringing in a fuller scope of diversity.
While it’s 1000% true that Hallmark never fails at bringing audiences a sweet, we’re-totally-in-love-forever-now happily ever after for every couple they show, the network has not been good at making sure we get to see a lot of diverse romances over its several years of filling pretty much every month with new romances.
