Actually, the same thing has struck me at some time and I even posted some musings on that in my own blog. I watch a lot of American TV shows. My all time favourite is naturally Sex and the City. But I tend to get repulsed by the all so popular medical TV shows that started with ER. The only exception is Scrubs - I love it! I would like to watch House M.D also but the blood scenes there are still too much.
And now, the biggest shock - we also have this parental guidelines signs for TV shows; ours are based on age. Medical TV shows that are full of scenes of death, pain, shocks, bodily parts, blood etc get a parental pre-screening clearance for age 12. The L-word show which is about lesbians gets a clearance for 16-year-old. Why? I simply don't get it. What's so scary there? Love between women?
