(Spoiler) I'm binge-watching Good Partner, but the ending is such a letdown

The reviews were good and it was actually quite enjoyable,
but out of the 16 episodes, it was fine until episode 10.
Once the protagonist Cha Eun-kyung's divorce lawsuit concludes
and her husband and Kim Sa-ra exit the show,
the plot is just dragged along with forced developments.
Episode 11 in particular was the absolute worst...
It used useless devices and emotional manipulation
to force the idea that a daughter needs a father.
After that, episode 12 is a psychopath killer case,
and the remaining 4 episodes are basically just an epilogue.
In reality, the series feels complete by episode 10 when the divorce wraps up.
