No, I don't agree. Medical dramas are a mainstay, similar to detective shows, and legal and criminal procedurals. They date back to radio. They tend to go in cycles in regards to popularity though.

For a bit - there were a lot of legal procedurals on, until they kind of killed the genre with redundancy. They still exist. They won't go away completely, just not as front and center.

Then it was criminal procedurals or detective shows - who are beginning to overstay their welcome, although they will still exist too. They don't go away.

Now, medical procedurals are coming back into fashion, but they never really went away. They just
weren't as numerous? I mean every year there is a medical drama, sometimes more than one. Grey's Anatomy has been on for about 20 years, and New Amsterdam just ended about a year or so ago. The Resident ended maybe a year before that. The UK had a "PITT" style series that was making the rounds a few years back. They are always there. There's also Chicago MD, which has been going for several years now. There's never been a time without them. Anymore than we've ever had a time without a criminal or legal procedural.

People like procedurals. They are easy to write, produce, and cast - and cheaper to make. And even better? They can run forever - you aren't dependent on the same cast, you can switch in and out at will.
