I actually have to admit, this trailer seems quite interesting and that TVB is doing pretty good. I was originally gonna watch this just b/c of Nancy and Felix, but then after watching the trailer it somehow really catches my attention. I really like the theme of it, and in the trailer with all the murders and stuff seems a lot like suspense! Also the one part when Jessica was running towards the door and someone pulled her back, that seems more like a scene in a horror movie. Looks interesting, can't wait! :D
