The problem here isn’t, and was never going to be, the rating.  The film was always going to be different and a different tone could easily be part of that.  The fatal flaw is the lack of focus that means the film keeps threatening to be about something quite substantial without ever getting to it.

It’s enjoyable, I suppose, in a throwaway sense but as it’s based on such high-end source material and it has Jose Padilha, the director of the blistering and highly recommended (if a little fascist) Elite Squad (2007 and 2010) movies, behind the camera being ‘so-so’ is just as damning as being terrible.
