When last we saw Riddick, he was the new emperor of the universe. But in his quest to finally see his Furian homeland, he is betrayed. "You keep what you kill" is a motto that has set up a future sequel, no doubt. The critics didn't give kind reviews to this movie. But, it is what it is. An action, sciFi flick. You are not going there to see 'Citizen Cane'. Btw, don't take underage kiddies.
