True; the target audience is younger. And while Mr. Scalzi loves to criticize, it's hard to argue with success. And say what you will Mr. Lucas' movies, one must admit that he succeed beyond anyone's wildest dreams with both trilogies.
Personally, I found the writing in I, II, and III lacking, compared to IV, V, and VI. And yes, the idea of a cowardly droid (cowardly lion? Hmmm) and another droid that can fly, weld, shoot lightsabers with high degree of accuracy, hack hardened computer systems, even survive massive power surges, all while being unable to speak common/english/whatever OR being able to tell the difference between a data port and a power outlet.... It does stretch one's ability to suspend disbelief. (And let's all just pretend the word "midicolorians was never penned!"
I still love the world he created, though. Heck, I even like star wars RPGs, when I've been able to play them.
I think part of Scalzi's problem is that he wants SW to be sci fi. It's really 1/2 sci fi and 1/2 fantasy. That fantasy half changes the dynamics somewhat.
No more monologuing, or I'll Swiss-cheese you on principle.
