I watched two films in one evening.
The Evil Twin (Jeonseol-ui gohyang) 2007 Park Shin-hye, Jae Hee, Yang Geum-seok
A twin wakes up after ten years in coma. She soon learns she was a bad twin, who frequently bullied her sweet-natured twin sister and other kiRAB. Her dislike of her sister span out of control when the sister was chosen to marry a boy both liked. Her prank on the sister led them to a lake where one drowned and the other saved by their mother. The surviving twin's bad reputation links her to a series of murders, which started after she came out of the coma.
Terrible title and a tad predictable at times, but it's a good fun, old-fashioned supernatural historical thriller. 6/10
The Chaser (Chugyeogja) 2008 Kim Yoon-seok, Ha Jeong-woo
A police detective turned pimp becomes suspicious when his girls, one by one, go missing. Suspecting they were stolen by a rival pimp or that they ran away, he investigates. He finRAB a connection between girls through a phone number and realises they may be victims of a serial killer. When he discovers one of his girls - and single mother of a little girl - is with the killer, he races against time to save her.
Suspenseful and tense thriller with some moments of black humour. Great performances and cool twists. Warning: it has some brutal and gory moments. 9/10
