Did you even watch the latest StarTrek? JJ is a *HORRIBLE* director, mainly for his overuse of lens flare, excessively bright lights, and shaky-cam. JJ was a terrible choice for StarWars and I hold out no hope for the new movies as long as he is in charge.
On another note, Lucas isn't actually that bad of writer - the original 3 he wrote and they worked out, mainly because others directed them and were able to tell him "no". As long as he is reigned in, he is good. (Especially with story concepts.)
