i think the crux of the issue is whether we think anakin, who is basically just an awesome fighter in episode 3 (but still gets cut up in tiny pieces by obi-wan), can take on a wizard of harry potter'* caliber.
granted, i havent seen any of the harry potters and i havent read any of the books. but what good will latin do when you cant speak? sure, he pulls that ability out of his hat in episode 4 [i think, dont correct me because it doesnt matter], but i still think hes capable of it if he gets mad enough in episode three.
summation: what good will spells do when you cant cast them?
