"Riddick" is a disappointing movie. It suffers from some terrible pacing problems, a lot of bad acting, and a cheesy, predictable plot. Though it’s not all bad, Riddick will do nothing to satisfy long-time fans of action, sci-fi or even of the franchise.
The film begins some time after "Chronicles of Riddick," with the titular character stranded on a desert planet after having a falling out with the Necromongers, his allies at the end of the last film. The back-story really doesn’t matter, though. Riddick is a standalone film with no plot points leading back to the other two movies.
The film’s biggest issue is it’s incredibly slow pacing. The movie seems to move at a crawl with little humor or action to break up the monotony. When the action finally does happen, the audience has lost interest.
The acting, for at least most of the major characters, is decent, with Vin Diesel the standout. The worst was definitely a religious bounty hunter who was just there to fill a film stereotype. His role in the movie was awkward at the best of times and painfully grating at the worst.
"Riddick" isn’t all bad, though. The action at times was great and the bounty hunter’s first night hunting Riddick creates an incredibly tense scene. Unfortunately, that intensity doesn’t last the rest of the film.
Overall, "Riddick" is a poor film with a few standout moments. If you’re a big fan of the Riddick franchise, I recommend renting it when it comes out on DVD.
