Talk about going from Bulgasal to Bull_____ in an episode and a half, all thanks to the dumbest WTF twist created for the sole purpose of enforcing a romance between characters who would never fall in love otherwise.

The most annoying thing is that the drama had a great twist before the one that jumped the shark and nuked the fridge all on the same tab. So SPOILERS ahead:

Our ML is a Goryeo monster hunter who, for unexplained reasons, was cursed by Bulgasal as an unborn baby. First episode is worth seeing for his birth. Not gonna spoil but boy your jaw will drop. Anyway, Bulgasal (a very beautiful woman) also saved his life when he was a child and he developed a life-long sorta crush on her. Which turned to hate when she killed his wife and son, after he'd returned the favor and saved her from other monster hunters. And then she mortally wounded him and sucked his soul thus switching their fates - he became the new Bulgasal (soulless) and she became human (soul). But then, he turned around and killed her and with her dying breath she said she would be reincarnated as a human from now on while he would remain an immortal monster muahahaha bursts into ashes like a vampire (which Bulgasal kind of is cause they feed on human blood). So our ML gave an oath that he would hunt her down like she hunted him when he was human and she a Bulgasal. So far so good. Then it gets better.

In Joseon era, ML tries to track her down by posting Wanted drawings of her and that bears fruit - a creepy looking painter shows him a gorgeous painting of her that he made and then reveals that he killed her! Turns out, now that the ex-Bulgy has the monster hunter's soul in her, all monsters who reincarnated as humans or semi humans (don't expect dramas to have rules of the universe, they bend to the plot demands) recognize his soul and want revenge on him who is now in her. So the creepy painter with vampire teeth was actually reincarnated Dukshini monster whom ML killed in Goryeo.

I really loved this twist! ML can't claim his soul back if she keeps croaking before he can get to her. So for 500 years since then, he unsuccessfully raced against time, until 2006 when his life and the quality of the drama changed forever.

How Bulgasal Jumped the Shark and turned into Bull_______

in 2006, we meet ex-Bulgasal's teenage reincarnation...except that it's a twin! Yes, she is now reincarnated as 2 twin girls, one who remembers her past lives, what she was and did and that Bulgasal is hunting her, and the one without memories who is technically speaking innocent of her twin's crimes and isn't a monster. Also, the innocent one has ML's soul cause reincarnated (ex)monsters can sense it in her but not in her twin sister (who said she wasn't really her sister so not really human). So this is a massive copout in order to get the innocent twin and ML fall in love since he wouldn't with the monster twin who killed his family. Conveniently, soulless twin dies a sacrificial death without reincarnation (no soul no reincarnation) so that her soulful twin could live and kill Bulgasal that the soulful twin believes killed the soulless twin, their mother and almost killed her. But we know that wasn't ML cause the killer's face was obscured and ML would never kill innocent bystanders. Zzzzzzzzzzzz.

So in one fell swoop, balloon popped, drama dropped.
