Gumihos seems to be the theme of several K-Dramas. My first exposure was with Forbidden Love where Kim Tae Hee played Gumiho. My second exposure was with Gu Family Book but the Gumiho acted by Lee Seung Gi (Kang Chi) was a Hanyo like Inuyasha. In this case, it's a pure-blooded Gumiho man named Lee Yeon (acted by Lee Dong Wuk) and Yi Ah Eum (Jo Bo Ah). I should've watched this years ago but I was more obsessed with Korean crime drama. I decided to watch this because I felt "bored". I was making fun of it because Dong Wuk looks like Katsumi Hyodo and Bo Ah looks like Kazusa Okuyama. The love story was something that only Canalo could dream of in Kishinryu Sentai Ryusoulger vs. Kaito Sentai Lupinranger vs. Keisatsu Sentai Patranger . Yes, it's moments like this that really make it almost impossible to break a clean cut from Tokusatsu in general. Lee Yeon is hundreds of years old but is considered biologically young (and so is Canalo) while Ah Eum is human. However...
My critiques on selected East Asian drama and movies but don't expect SJW-friendly series reviews... =P
