I think this line should be removed:

Wookies are known to do that? What? Is this like some kind of innate trait that all wookies have? We don't need to be told "wookies are known to do that." It is excessive and sounds like prequel George Lucas dialog. I was hoping to hear this gone in Revisited.

Human's are known to cheat on their spouses, it doesn't mean they all do or that they do it all the time.

The line is very important not only to the film but the saga in general as it underlines that droids are essentially slaves and if they have ideas above their station they can be damaged and destroyed and their organic masters will react in much the same way as if someone pulled the wing mirror off a car or blew up a fridge.

They feel physical discomfort, they are intelligent and have a degree of free will but they are property (time for a revolution golden rod).
