That's it, exactly, as far as the EMH was concerned - at least, for me. He was ALWAYS given too much focus, right out of the box. "Oh! A Hologram who wants to be Human!" It doesn't work for me. With Data, that was the reason he was created, in the first place. But The Doctor is a hologram, for crying out loud - on what basis does he need a girlfriend, for example.
Picardo can be very entertaining, but the EMH needed to be scaled back, or given a direction that involved a writer's gift for imagination. There was none of that.
