There is no doubt that this is another action movie with alot of similarities from the original first installment Pitch Black, but I gotta say as sci-fi horror and actions go, this one definitely has more to add to the genres, doesn't get boring, no mucking around with the pacing, and the action is very entertaining, my only real complaint is the last 30 seconds of the movie felt rushed but overall some really good looking set pieces, some good slick humor and violent action scenes that shouldn't leave fans of the character Riddick disappointed. Solid movie all the way through, in terms of what it is and not trying to be more than what it is, I'd give this a 4/5 stars honestly
