First of all the movie, great acting peformance from Brad Pitt, very intense performance. The movie requires a lot of attention to pick up all the talking that goes on and the storys that are told. this film is not an action movie, its a drama, so there are no major gun fights etc.
In respect of blu ray, although it looks good, this type of film does not do it justice, nice backgroaunds etc, but nothing that will give you the wow factor.
I would recommend this film, but on dvd, then use your dvd upscaler to bring the picture up. for this type of movie it will be cheaper but still effective.
i hope this helps
