I'm posing the question how much is too much?

Today I was helping a friend with her book. She'd called me to ask if I could help her with a dilemma she was having. She felt like her book was missing something and after reading four pages I realized what it was body language. Now I'm asking my self how much body language is too much in a novel. Or is it never too much? I would like to know your thoughts on this if you reading this blog...

How much is too much body language, or is it never too much. I can't seem to think of a time when I felt that the author was talking too much about how the characters moved and what they did.

So, I'm posing the question how much is too much?
