I recently became completely hooked on the show “House”, which in my mind is extremely fascinating for the medical puzzles that drive the plot (and come on, the personality of Dr. House is awesome). The blog “Polite Dissent”:http://www.politedissent.com/ chronicles the veracity of medical elements in popular media, including television and comics.
In particular, the blog features some excellent “reviews”:http://www.politedissent.com/house_pd.html of the medicine practiced by the misanthropic Dr. House and his overly attractive group of doctors. Given the reviews it seems that, in general, the show does a reasonable job of featuring accurate medicine (though it most certainly remains a work of fiction).
