Blood Relationship

In today's Gospel Reading, aside from the fact that genealogies are notorious for feeling like the boringest books in the Bible, one thing that always stands out to me when reading Jesus' genealogy besides the sprinkling of women of faith throughout, is that after all that work of listing the direct bloodlines, we end up with:

Joseph, the husband of Mary.
Of her was born Jesus who is called the Christ.

Do I have to trade in my Christian card if I admit to feeling a bit of a let down?  Knowing that Mary conceived Jesus with no "input" from Joseph, it feels like this genealogy sort of breaks at the end.  All this effort to tie the blood relationships together for 42 generations and then Jesus has no Joseph blood in Him.  It's almost as if it would be more logical if it was, "Jacob, the father of Mary, the wife of Joseph.  Of her was born Jesus..."  So there must be something else.

Clearly, the original makes St. Joseph way more of a key player than my way.    Joseph's line is obviously very important being a descendant of Abraham and David, but the fact that we call Jesus the son of Joseph (and the son of David) seems to indicate some sort of sanctity of marriage and parenthood that's stronger than blood relation.  Hm...
