If you suspend your disbelief about the entire premise of coming back from the dead with a silly marble (which happens to have the world’s poorest set of instructional manual), Abyss is a pretty good watch.
As mentioned in my previous post, the balance between the thriller and the romcom is done well. We have a team of competent Good Guys set against one Psycho and his desperate son. Imo, compared to Oh Yeong-chul, Tae-jin as the final bad guy is kinda of a letdown. Whenever you have a character who kills because he is desperately trying to save himself and his life, it is only a SHORT matter of time before everything backfires on him and he is captured.
In contrast, Oh Yeong-chul with his very random killings is the archetype psychopath. He kills, because…he wants to. His rationale for killing can range from being ignored, to because its necessary. Which makes him harder to capture — and even without him being a psycho, he is already a smart schemer. He manages to lead his children (both biological and adopted) by their noses for most of the story, until Se-yeon and Min step into the picture.
Thankfully, the duo are just as good as Oh Yeong-chul. After a few initial setbacks, Min and Se-yeon are quick to latch on to Yeong-chul’s new face, and also the fact that he is not fully aware of Abyss’ powers and limitations. (not that we are as well) And the cuteness as their romance develop is a good foil to the heaviness that usually accompanies a thriller (and the body count).
The only little drawback to Abyss is its fantasy element. Eventually, Abyss has to explain itself by the end of the story. We find out (at ep15/16) that the marble has a finite use (duh), and when Min uses the last return-from-dead card on Se-yeon, he is locked in purgatory for the next 3 years. Although he manages to claw his way back to the land of living, his exact route and method are not very clear.
The old ahjusshi who collects cardboard at Se-yeon’s neighbourhood also strangely turns out to be a Guardian Angel of sorts. While I had to expect a certain amount of deux ex machina element in the ending, Mr Ahjusshi doesn’t do due diligence in explaining the entire fantasy element either.
But never mind that, just watch for the cat-mouse game which runs through the entire Abyss narrative. It should keep you entertained.
