The intensity of the final one hour of glorious twists and turns contributed much to the success of the first part. There was something organic about how it all tied together in the end. But in this sequel, even when things remain unpredictable for the most part, it is achieved using a few conveniently-created characters and a slightly-contrived setup with loopholes. Having said that, it is no easy task to flesh out a script like this from a case which was as good as closed.
