Steven Soderbergh's first episode of The Knick is available for free online. Get a look inside New York's Knickerbocker Hospital in the year 1900, and the various surgical procedures that were hosted inside its theater. But be warned, it's bloody.
The pilot is on YouTube, which means it may not be available everywhere. However, the first episode is also available on demand and on HBO Go.
Oh and finally, it's probably not a good idea to watch this while eating...
