Contrary to the endorsement on the above poster, Riddick was not "the most entertaining action movie of the year" in 2013. It was just an adequate third instalment in a rather ambitious franchise, that has failed to grab the wider public's attention. That’s not to say that they didn’t make money. This is after all the third movie. Writer and Director David Twohy has done his best to try and make the character of Riddick (Vin Diesel) more than the sum of his parts and I admire both of them for their persistence. Unfortunately, Riddick just isn't engaging or complicated enough a protagonist to sustain a franchise of this nature. The anti-hero was sufficient to drive the original Pitch Black back in 2000 which had some good ideas but just couldn't sustain the overarching and overblown Chronicles of Riddick in 2004. This instalment is competently made but ultimately superfluous.
