There are many twists and turns in this film. The first half is suspenseful and intriguing, but ultimately it all becomes a bit too contrived and convoluted and quite unbelievable as it goes on. It's too long and there are too many plotlines, so it kind of loses focus of the main one, which is a murder story. They should have just focussed on that and develop it more, because some of the characters and their motives could have been explored more and painted a little more creatively, because especially the bad guy was rather boilerplate.
