Query: Never Listen to Critics

This film got poor reviews, but I enjoyed "Pitch Black" and I am a Science Fiction fan so I went anyway. This film was excellent from the very start and is one of those rare examples of pure science fiction. The main gripe of the critics centered around the fact that "nothing was explained" a general complaint from critics who are not used to reviewing science fiction, as most science fiction (and this one is no different) supposes a universe that the reader or watcher buys into. The special effects were incredible and the bad guys sufficiently evil. Of course, I don't want to give anything away but one hopes from the ending and the credits that Vin Diesel and David Twohy have at least one Riddick left in them.
