Since I brought up House yesterday I might as well keep up the superficial focus on medicine a la your television and point to this column in Slate.
I don't watch Grey's Anatomy, but it sounds like it features both of the quibbles I have with House...but to a much more serious degree. Namely a) inappropriate behavior by the doctors and b) totally inaccurate portrayals of medical situations.
The article is a bit more interesting than the usual ramblings on the topic, including mine, because it covers the history of the medical profession as shown on TV. Turns out the AMA used to have significant control over how medicine was portrayed. Once they lost that all hell broke loose.
Interesting piece. Check it out.
