What is "a mixed bag"? Is it a common expression?

"Mixed bag" means that something has positive and negative qualities to it. Emma is telling the interviewer that Hollywood has its good qualities and bad qualities. I am unsure if this is a common expression. This is the first time that I have ever heard of this expression before, but that doesn't mean that it is uncommon. Ex: Her speech was a mixed bag. Ex: The new vehicle is a mixed bag; great gas mileage but poor steering control.
