I guess what I'm trying to say is that, while in theory one would not know what kind of SW film a director will do, with JJ Abrams I'm strongly inclined to say I have a decent idea. And again not in a bad way. Regardless of story, I think from ST to Super 8, we have a solid idea of how JJ does sci-fi.
JJ really does embody many aspects of filmmaking from whom I presume are his two idols, Lucas and Spielberg.
ST 09 was the prequel Lucas never made!
