I am a huge fan of Linda. In my book she can do no wrong. She is an exceptional actress. That being said, she is also a very mannered actress. It might have been her training or background. Like many great actresses, including Jessica Lange, who is also very mannered, Linda uses her hands and body alot in her characterizations, often in similar ways.
