The Good: Vin Diesel is a natural action star. He gives you the cool, rugged and edgy demeanor that we've come to expect and appreciate in an anti-hero. The action scenes were good and some parts were unexpectedly more gory than the trailer promoted. Riddick's survival skills are put on display for the first quarter of the movie, so if you're into shows like Man vs. Wild then this will pretty much be the same deal, except on another planet.
The Bad: As with many action flicks, this movie's story line was pretty flat. It's pretty predictable, just like the previous movies ( Pitch Black and Chronicles Of Riddick). Outside of Vin Diesel, the acting is pretty bad. Characters make cheesy jokes that warrant a chuckle or two at best. The entire two hours of this story probably could have been cut short if so much time hadn't been spent on showing just how much of a survivor Riddick can be. That part probably could've just been assumed with a few cut scenes. Lastly, one of the coolest things about Riddick is the fact that he can see in the dark. Unlike in the original Pitch Black movie where his eye sight made him so unique, it's barely highlighted in this film. That's kind of like having a batman movie without him using any gadgets or Superman barely ever flying.
The Reason: If you were a fan of the previous installments of this film series, then you'll more than likely enjoy this 3rd sequel. It's pretty much the same cookie-cutter formula that the others used, so don't expect anything radically different. The rated R rating is justified as this isn't really a movie for kids given the adult language, brief nudity, and violence.
Wait for this and watch it at home. Good movie, especially for fans, but not really worth spending theater money on.
The Rating: 6.5/10
