Trying it on for size does put light onto the whole Anakin/Dukoo problem. On the one hand, Anakin would really have a great reason to attack him, wouldn't he?
But then, imagining how it plays out, I realize one of my problems with having Anakin rush Dukoo is how pathetic Anakin's attack turns out to be. He runs in, looking goofy, disobeying a direct order, against an obviously powerful opponent-- and gets swatted aside like a fly.
That may be what GL wanted, but it sure is unsatisfying.
Regardless of what motivates Anakin's attack-- and without getting into how to do this-- would anyone else feel better if Anakin had managed to achieve the slightest thing before being defeated? I mean, if he had only made Dukoo draw his light-saber and hold Anakin off before slapping him aside. If Anakin got that far, I could respect him a little more-- sense his raw, if untrained power.
I don't claim this is the biggest problem. I think there's a snarl of problems surrounding Anakin's choice. This is one of them, I think.
