Hopefully they'll get rid of that phony Vargas- with her overacting facial expressions feigning false empathy ... I prefer ABC's evening news to the other networks ... and I like Vargas ... however, your assessment of her is on the money. She needs to tone down the facial expression thing a notch or two.
Next time you watch her turn the volume off. you will then see how much she overacts with her face. I think she tries to imitate Diane Sawyer -without the class.
