I was just perusing Amazon and came across a novelized version of the currently playing film, After Earth. I did not purchase it because of the following: I've only read two novelizations of films and both were nothing more than exact renditions of the film in book form. There was nothing extra, nothing new, nothing different. Both were Science Fiction. AVP and the original Stargate film. Clearly two examples does not a fair assessment make, but I'm wondering, if they are in fact all this way... what's the point?
