What did you think of the restaurant scene? When the two are alone... I loved it. Very tense.
Oh yeah! Good call. Probably the most tense scene in the film. On top of being evil, Landa is one of those characters you just can't take your eyes off of. Watching him operate in that scene was riviting.
I also felt the tension when Zoller comes up to the projection room at the end. I really didn't want to see the plan fail at that point. So when Shosanna got shot I was genuinely surprised. I wasn't sure if everything was already in place at that point or not. Luckily it was.
I wasn't sorry to see either of them die though. I wasn't attached to their characters.
Shosanna was an interesting character for me (not to mention the actress O.O hot), but I wasn't really attached either now that you mention. I did have an overwhelming feeling of "Yes, please, burn these Nazi's in a great inferno of justice" but her backstory was.. meh. One character I wish we would have had more of was her lover, who I forget the name of. He was so devoted and his "Oui, Shosanna" line and big smile was awesome to me.
