I read some reviews on Amazon for movie 6 and a few of them criticized how Ducky was portrayed. I watched it, and I watched 7, and by golly, there is a difference between Ducky of 6 and the other movies!
Watch 6 first. There were a lot of Ducky incidents that kinda disgust me.
One of her first lines in the movie is a teasing "Oooh, Auntie Cera!!" to Cera. She was sarcastic to Petrie when he said there's a river she could fall into. She translated what the idiot twerps said about going to Saurus Rock, getting Cera in trouble with her Dad, and then eneded the scene on a high note by happily babbling about bad luck---something the real Ducky would never do. Oh, and to make matters worse, she gave Spike an angry stare after "Bad Luck". She was still cute, of course, but very emotionless a lot of the time and very bland.
Ad then in 7 she went back to her old style. The switch was so obvious. She seemed seriously worried about Petrie, comforted him, and was her innocent, sweet self again. So what's the deal with movie 6? Did the writers just feel Ducky needed to be changed up?
