I've never seen The Nurses, but I've always wanted too. I have a bunch of old TV/Movie magazines from the 60s and there are a bunch of articles on actress Zina Bethune (one of the stars of the show). She was popular when her show was on the air, but I never heard about her since. I was curious to find out what happened to her, so I googled her name, and discovered she died tragically earlier this year! So sad. Hopefully, I'll get to watch the show someday.
The Nurses is a very good show. Not quite at the level of The Defenders, but quite similar. I know there are those on these boards who prefer shows which are traditional crime drama/courtroom series but if you enjoy shows that are actually about something, i.e., social issues, The Nurses was essentially The Defenders in a hospital. Unfortunately the show was never syndicated or rerun anywhere, even though there were 98 episodes made and the show ran 3 seasons. While not as consistently excellent as The Defenders, there are some great episodes.
