I have watched the show ER from the beginning. It is in it's 15th and final season. As a result, they are bringing back characters that we have loved over the years. Last Thursday, they brought back William H. Macy as Dr. Morgerstern. Unlike the episode that they brought back Dr. Greene, I loved this episode.
The old chief of medicine who is now senile and very fragile, ends up in the ER. The staff finally figures out who he is. Dr. Morgernstern shows up as he is the man's proxy. He explains to the staff all that has happened with the ER is because of this man. There is a final touching scene where the ER gathers to pay respect to the man.
