In the earlier episodes, Meredith's narrations centered on some sort of theme. The "patient of the week" would tie into it, and a lot of times what was going on with the staff would, too. It was very clean writing and wove together well.
For example, today they showed episode 2.11 (Owner of a lonely heart). The theme was loneliness, and how we really aren't alone. In it We had the patient who swallowed the razor blades for a vacation from solitary, etc.
The show is still fantastic, but has anyone noticed they haven't been doing that kind of thing lately?
