I really love this new show -- its has great characters and story lines. NBC should keep this show, because it gets better each week. I like that we are learning more about the depth of the characters, which is important. It could be another ER or Third Watch which were also spectacular shows..This show could run for along time because there are so many stories that could be told. I like how doesn't focus on just one character, but explores all their backgrounds. The fast pace of the show is what I love so much as well. We don't have shows like that since ER and Third Watch are no longer on. They have chose excellent actors to play the roles and they are doing such a good job.
