I just hope for a good story. I'll admit that I'm biased in that visuals, camera angle, etc. won't affect me at all. But when you try to tell the stories of Episodes 4 - 6, it all seems fantastic. 1 - 3 just seem to have people going off all over the place for no real reason other than to have lots of places to show on the screen. I've even heard someone attached to the prequels describe how awesome they would be because there was so much happening on screen in every shot. The aim was as bad as Greedo's must have been to miss Han!!
Here's something interesting you might not realize. Without watching them, you can listen to almost all of the original Star Trek episodes and follow the entire story and even have a good idea of what people are doing on screen. A scene here or there might not workThere are loooong periods of "I have no clue" in episodes 4 - 6 but, for the most part, you can figure it out and it's great! Episodes 1 - 3 are impossible to follow without someone telling you what's happening.
I can't say that visual storytelling is bad. Anyone who enjoys The Pink Panther or Road Runner cartoons knows that I'd be wrong if I tried... but I think the story in Star Wars movies should have a little more substance to them.
I agree on story. I don't think there needs to be any concern for technical visuals, Hollywood has that down pretty well and JJ's decision to use film, sets, and models much more often will only enhance that I think. I also think he is perfectly capable of actually getting actors to act as opposed to read lines badly like the did in the prequels. So it really boils down to a good story premise and good pacing in the film. We shall see.
