if you include the tusken slaughter as part of anakin's reaction then it's a pretty powerful reaction i'd say.....i caught hayden on some soap opera once (weird, i don't watch tv much and i don't even know what the show was...total coincidence)....he was throwing furniture around and crying in some girl's bedroom....he was crying when he told padme about the slaughter, and he's crying (or close to it) in photo's i've seen of the new duel....this is what hayden does, and a big part of why he was chosen for the role....(not arguing a point, all of this just reminded me)......
and darth surgent, i agree and i've always said vader was luke's father right from the start.....he made up the leia sister thing at the end, but vader was always luke's father.....and it raised my eyebrows at the time, but in my subconscious i already knew from all the dropped hints (i was only about 7 - mind games still worked on me then)....
