There is no point getting outraged about a fictional character, sure.
But there is every point getting outraged about shitty writing or a shitty storyline.
For example, you can hate Ramsay Bolton from GoT all you like, but can still admit that he was a well written psychopath and the world reacted accordingly to him. You can hate Charlie from Two and a half Men, because of how selfish he is and how he treats everyone around him, but his antics are still funny and fit into the storyline of each episode.
The dad, however, does not fit into the storyline of a silly romantic comedy at all. It seems like a poor retcon along the lines of: "I wann introduce his family, and they should be close by, so both families can meet later. But, whoops, why would he never visit his family? Let's just make the dad a sex crazed maniac and try to sell it as a joke. Also give him a baby sister to set up a joke later."
It is Prison School all over again: Funny jokes, but shit overall story. At least the art in Prison School was good.
