Review of Long Way Home

Every one of his shows I've watched has a ton of plot holes and lose ends. All the more infuriating because there's no need for them. Why did Artur suddenly, after 25 years, feel the need to contact David? What questions did he ask him? How did Artur's Chinese girlfriend cross paths with the rape defendant's father? How did David know where Artur lived? Why did Artur have an apartment and a hotel room? Pawel's father digs a grave, kills his wife, yet her bones are found in the lake? Pawel's t-shirt is found entangled in a pile of birch branches; how did it get there? Who buried Daniel, we see Artur run away. Artur dropped the knife, yet it's not mentioned. And that's just what comes to mind without trying too hard.
