If you now BKK you will love it, as plot takes place at night in BKK city.
Acting of the main characters is very good, and some Thai actors there that deserves to get jobs in Hollywood films. It is a slow paced, different kind of movie, very low budget so the blood and injuries makeup work is very basic so it looks fake, but the point is that you see with very basic tools they ended up with a good result. If you've been to BKK watch it, I do hope to see Vanida Golten in movies, she steals the show.
