Overall this movie is watchable, thumbs up to all the casts for the great acting.
As a "Thriller" movie, there's no thrilling moments at all, no surprise, nothing, maybe just a little bit mystery that drive the story but beside that nothing. The story line is too flat, I expect to have more surprises and or some "bloody" scene or sort of for this kind of genre.
So for those thriller / horror lover, you may still watch this, but do not expect any thrilling moments in it.
Too bad the great acting not supported with the great story line, it can be a very good movie with better story and more thrilling effects as a thriller movie should have.
