ER doesn't belong in the same category as Three Kings and From Dusk Till Dawn. People need to go back and watch those first eight seasons of ER because the show doesn't get the recognition it deserves for how influential it was for those first eight seasons. They were doing extremely compelling prestige drama on network TV in the 90s several years before The Sopranos came along. 25-30 million people were watching each episode, and Clooney was the show's biggest star.
