I and a few others have repeatedly backed this up, you choose to ignore it. If some people are only looking at the surface level, then that's their loss. That doesn't mean Lucas should drop all of the depth and meaning just because some people won't take the time to appreciate it. Lucas admits when he is unhappy with his own work all the time. It's why he is re tweaking the SE's, and it's why he continues to re edit the prequels for their DVD release. But when it comes to Jar-Jar, Lucas says he is really happy with the way he turned out.
