That was one of the saddest TV shows I think I've ever seen. 🙁
I've been watching ER for a very long time. Like you said, NSF4, it's amazing how attached you can get to these characters.
I'm also amazed at the way this show keeps going strong. With all the cast changes it's had and now the last original main cast member leaving, I wonder how long it will last. I hope it's a while, though. 🙂
