zam does lose her arm in ep II. when she tries to sneak up on obi-wan, he whips around & takes off her blaster arm near the elbow. it doesn't show any detail, you just see the arm fly off for a second and thats why she gets helped out to the street.
as well, i'm pretty sure a couple clones got the no arm treatment (when jett lucas kills a buncha clones on the ramp and when yoda/obi-wan are clone thrashing in front of the temple)
I didnt think that it needed to be more graphic or anything.
The hype left me wanting more, I dont think Anakin looked as menacing as he was capable of. And I also dont think the kid who went up to him was cute enough, maybe a girl would have been better(that sounds mean). I saw this as the point of no return in the eyes of average fans, yet I heard little reaction when the scene went down.
