Pro: fun to encounter well-known characters from the original Dune again

Con: odd, 'non-Dune' word choices bumped me out of the story every once in a while, e.g. 'christening' (really? this is what the Fremen call it on Arrakis? I don't think so) or 'titanic mistake' (even worse, that a desert world would consider the oceanic sinking of a ship on Earth as the reference point for 'very big'), seemed to underline the author being the son of the original series author rather than original author himself (who would not make such basic errors)
