degrassifan, while you are right about Carrie playing it with less gumption, and overall I think Carrie did a good job, there are still some places where she gave bad line readings. (And I blame this partly on the director for not helping her.)
Part of her acting problem was just not getting her mouth around the text. There is one point where she has a line with the interjection, "Captain" and it comes off really unnatural.
I'll have to go back and watch again but it was something like "You should know, Captain, that blah, blah, blah." And the way she said it was really wrong.
If anyone ever tells you that you put too much Parmesan cheese on your pasta, stop talking to them. You don't need that kind of negativity in your life.
