I agree with this complaint as well. I think it’s kind of silly that it just so happens that anyone of importance is somehow related to each other.
“What a coincidence!” -_-
Next thing you know, we’ll find out that Sue Graham is really the daughter of Lynn Kyle and Marie Crystal.
Robotech would feel a bit more epic if some main characters had NOTHING to do with others.
That having said it doesn’t bother me enough to really affect my enjoyment of Robotech! B-)
I guess the other way to look at it is the endearing “ah big happy family” feeling like the bridge of the Enterprise. Not realistic, but seems to be a sci-fi tradition.
