For everybody complaining that it looks too modern, are you forgetting how unbelievably 70's the original SW looked?
That's a different way of thinking about it. JJ could be using much more practical FX than most film's today, but much like the original SW screamed 1977, this one will scream 2015. So in a way, JJ could be more homage to the fact that SW 77 heavily reflected the culture of that day.
