I don't especially enjoy violent films, particularly when it's simply gratuitous, but when it's done well, it can add to a film's impact. This film is just so well made. The script, acting, filmmaking are excellent. Matthew McConaughey's performance is superb, but then so is the rest of the cast. The humour is brilliantly done, without ever detracting from the menace and impact of the film. As I say, it's exceptionally violent, so not for all tastes, but it's also a brilliant film.
