What Is This And Why Did It Happen

IN THE NAME OF THE ONE TRUE MASTER SPARK, WHAT WAS THIS SHIT.
Papa no Iukoto wo Kikinasai just raped itself with a pole-mounted metaphorical chainsaw from the depths of Hell.
Not only was that a totally uncalled for deus ex machina - the plot could perfectly well keep running convincingly if Yuuri and Shingo had taken their honeymoon, then come home, and then Yuuta could concievably have the girls over once in a while - but also, something as cliché as a plane crash reeks of plot device. To add insult to injury, the series places itself in a dilemma where it can either choose to become a drama series and basically make itself into Usagi Drop x3, or rape the corpse of psychological theory and shit down its throat. Kids like that aren't gonna be normal after an astrofucking plane crash that killed both their parents, and either the series has to become a drama to fit or waste all the basic correctness in child-psychological theory that made the first episode watchable. To add insult to insult to injury and then piss in the wound, the final quarter of the episode also shows an unbelievably butter-fingered handling of the very most basic law theory in existence. You don't sympathy yourself into parental rights, nor do you debate, shout or discuss your way into it. Parental rights are parental rights, and they go to rather specific people. One does not just decide, like the faceless relatives do, "The loli goes to me, the jailbait goes to that guy over there and the toddler goes to the man in the crew cut and pencil mustache over there". There's a reason lawsuits about that kind of thing drag on, fuckers. If somehow it has already been decided, then Yuuta's sympathy bomb isn't going to help. He'd have to file a lawsuit of astronomic proportions and hire a rather good lawyer, since his case is incredibly flimsy. He's a college student and hasn't known the girls for terribly long - the only thing he's got going for himself is that he was taking care of them at the time, an argument that would instantly be ignored as a pathetic attempt at pathos.
I AM ANGRY.
