It started off so funny. Such a winning combination in the beginning. Then by the third season it started getting too depthful and rather serious in tone. I mostly quit watching after season 4. Damnitt, I loved it when Kraus was on Benson's back and hating him. I hated it when they became friendly! It was only a tv show! They'd tried too hard later to make it realistic. Very bad move. Besides people can hate each other in real life and still work together. Point is:in some ways, who can say just what reality is?
