Admittedly, at this point in the Riddick series, you have to be a fan of the character to enjoy the movies. The first, "Pitch Black", was incredible and introduced you to this intelligent, resourceful, merciless, killer and hunted man. And, if you did enjoy the first movie, then, well, you have it again in "Riddick", just substitute darkness for rain. However, for me, the attraction is in the character himself. So, if you are a big fan of the series, then this movie won't disappoint. If not, then you'll just need to load some other sci-fi, action-packed, thriller into your DVD or Blu-ray player.
