I haven't watched many kdramas but this is the best psychological thriller so far. All the actors played their part very well. The most creepy character for me was Moon Jo (Lee Dong-wook) but also the best character. LDW pulled it off in the best way possible. It was also fun watching the way Jung Woo (Im Siwan) developed his character through the episodes. Watching people get murdered was kinda fun in a weird way. The last episode is just..wow! I don't really enjoy thrillers but I watched this thriller coz my fave actor Lee Dong-wook❤️ was starring in the show too. He was my fave character even as the antagonist. I haven't seen many thrillers but if u're looking for a realistic thriller this is the one. If u are searching to watch the show online then watch it on this app called'Go Go Kdrama' I know it's kind of lame name but it's good. Go 'n' watch the show NOW!
P.S. my fave dialog was 'Honey' or to be more precise '자기야' in Korean😄 Anyways....have fun watching Strangers From Hell.... Gud day to u😁
