One of the greatest things about seeing a film for the first time is the surprise and anticipation, to removing that can detract a lot from the overall impact of the film. The problem they present is that film- makers have to construct their work, with the knowledge that the audience knows how it ends. Prequels to films are often made when there is either a rich back story behind the originals or the producers are wanting a little more money from a particular franchise (see the Star Wars prequels). To begin on a tangent before evaluating the film, before summer 2011, I had not seen a decent prequel film.
