Ask yourself: can you translate a conflict into the real world without any significant change? Typically in movies, that includes all sorts of family drama put in because the makers think they need more emotional connection, for instance, if in a movie about an alien invasion, it just happens the child of the protagonist fell into enemy hands, and that's why the protagonist ends up defeating the aliens in the end. Such things always make me groan.
Contrast, in DAI, the backstory of Chateau d'Onterre. Also family drama. Abuse of children for various reasons is common both in Thedas and IRL. However, it is actually not a story about child abuse as the primary cause of drama, but about magic and spirits.
As I said, DAI is generally ok in that regard. I was talking about requests for more character interaction, citing ME3's Citadel as an example - which features exactly the meaningless type of interaction that exists to get you emotionally involved, with no other role and thus irrelevant and uninteresting, except for the function it fulfilled on the meta-level.
I do agree that character interaction and drama are rather shallow if they're just there for the sake of it (even if it can be entertaining when its well done). The question I generally ask, however, is not whether the character development and drama is anchored to setting, but how does it relate to the themes presented by the story. (But maybe I'm splitting hairs.)
Your alien example reminds me of The Last of Us. Without getting into too much detail, the connection between the two main characters does two things. It kept me engaged in the story and on the edge of my seat. And in doing so, drew the attention to the theme relating to how people care more about the small group of people close to them than people as a whole. (This post just inadvertently went meta).
I cant speak for everyone who says they want more character interaction (I imagine there are some who only want it for the drama aspect), but this is the context towards which I wanted more of it in DAI.
