Since I have been watching House MD, all the episodes seem to be a bit unrealistic. Does this series have any close actual relevance to medical science?
The series is about cases that most doctors are unable to solve. So it may just be realistic.
There is a website managed by a doctor which reviews the medicine in House M.D.. The site features in an article on Forbes titled, The Most (And Least) Medically Accurate Episodes Of 'House, M.D.'.
So the opinion appears to be that the quality varies from episode to episode. Some are very good while others can be unreliable.
