As a stand alone film, without the subject matter being taken into consideration - Its brilliant. While nothing close to historically accurate in the sense of Wallace, it is close to the political feelings of the three nations at the time - England, Scotland and France.
I think it was recently voted the top Scottish Film of all time, so can't be bad The only problem I have with it, is the love interest between Wallace and Princess Isabelle; which I felt could have been cut out completely. Favourite character for me though, has to be Stephen, The Irishman
