I agree with a lot of that from Salon. The example I would have used if I were them was the discussion between Shane and Rick about Sophia. It started off interesting when they were talking about girlfriends, and then Rick asks Shane's opinion, Shane gives it. But then we get this drawn out scene where Rick is predictably indignant. The emotions of each character could have been shown in just a few lines and some facial expression.
We've been watching, we know the characters. We don't need drawn out character development that we already know. Show Rick ask, show Shane answer, use two or three lines and move on to another scene. We got it, we're not dumb.
They try to get drama and conflict from these scenes about philosophical differences, and it doesn't work. It's more like time filler.
