ENDER'S GAME Trailer Offers Nothing New in Blockbuster Landscape

I understand that there is some Hollywood rule out there that all Hero-Journey Blockbuster (tm) trailers have to look alike.  I understand that if you have Harrison Ford in your movie that you might as well use his voice to sell your movie.  What I do not understand is whether Gavin Hood aims to preserve the tone of Ender's Game, very much from a young (if extraordinarily gifted) child's point of view, instead of indulging in noisy action blockbuster familiarity.
