You see, I didn't mind the excessive throwbacks to Wrath of Khan in STID. When you think about it, it was a very logical way of doing things. It's not like Khan wouldn't exist and try essentially the same thing just because the timeline shifted. He would still exist (apparently as a white guy? but i forgive that because Cumberbatch was fantastic) and still want the same things, therefore a very similar story would unfold, only things would be slightly different because of the alternate timeline. It made for an interesting movie at the very least. But, either way, you can't look at Star Trek as an example of what JJ will do with Star Wars story-wise because there were different writers working on them. You also can't look at it for what he'll do with it as far as visuals because JJ seems to put a different look to each project he does. He gets a lot of crap for his lens flares, but that's something he did specifically for the stylistic look of Star Trek. The only thing you can look to ST for as an example of what to expect from SW is directing style, and JJ has proven himself an exciting, fast paced director who knows how to get a great performance out of his actors. Is there really anything more we want out of SW than that after the boring, lackluster, terribly acted prequels?
