I just spent several hours watching preview DVDs of Cinemax’s new medical drama, The Knick, which premieres tomorrow night, and dramatizes “cutting-edge” medicine as practiced circa 1900. How jarring, then, to return to the current century, in this excellent documentary series, and watch what we consider state-of-the-art medical procedures in 2014. Oh, and this week’s installment, it’s also Take Your Daughter to Work Day – at least for Dr. Mehmet Oz, whose high-school daughter visits his hospital workplace to observe for the first time.
