Bourne again

I love the Bourne movies. We have all three of them on DVD. And we watch them all the time.
Last night we decided to watch #3 again. The Bourne Ultimatum.
What is with the shaky cam on this movie?
I don't remember the other two being like this. I understand that the shaky cam effect is great for action sequences. But, even the quieter sequences (where they are sitting talking)...shaky cam!
Geez whiz...I was getting sea-sick watching it last night!
