2. Awful Editing
This film is edited with the fashionable yet irritating choppiness that unfortunately defines so many action films nowadays. When Riddick is fighting both humans and monsters, it's difficult to make out quite what's going on, as director David Twohy insists on having editor Tracy Adams cut so frantically that the only result is annoyance on the part of the audience. Given the movie's favourable R-rating, there's not really any excuse not to just show us the violence in all of its glorious detail, with steady shots that take their time. Twohy, whose prior films in the series were much easier to stomach editorially, instead opts for the ADD approach to action editing that has become depressingly abundant these days. It's difficult to become involved in even the movie's strong suit - its hardcore action - when we're forced to try and discern coherence from a mass of cluttered images.
