Just the ending.... DOH!
Loved this movie and you will too. Great casting, actors, action, story etc etc bar one little niggle which was inevitable unfortunately. Tom Hardys character is an awesome, unstoppable one strike destroys everyone in his path, seemingly emotionless machine of a fighter.... but loses to his brother who lets be honest was made to struggle to the final two and nearly lost most of his fights. I know it had to be done to make the film finish with a bit of a heart story but the build up of hardy's fighter as effectively unbeatable just made the end a bit duff. Fortunately the rest of the film made up for it. Maybe just watch it up to the last fight, then watch that one in 6 mths time when you have forgotton what the rest of the film was about.
