I see the parallel, but "The Girl in Question" does have, in theory, a reason for existing. Three episodes before the end of Angel's show, it makes a certain amount of sense to return to the Buffy issue. There's absolutely no conceivable reason to drag Vala's paint-by-numbers family issues on screen with only three hours left to go in the show.

Also, "The Girl in Question", for all its many problems, was not boring.
