"...but now that Donald Trump is President the genre is essential, excoriating viewing".

Just why is it essential viewing? I know Trump is an unbearable idiot so why would I need to watch a show mocking him? And to be perfectly honest, what sort of person derives their political information and opinion from a comedy show. 

In a recent article, the son of Neil Postman wrote a column suggesting his father's polemic, "Amusing Ourselves to Death", predicted the rise of a figure like Donald Trump.

But there is the flip side of Postman's prescient warning: those trapped in a television existence in which comedy becomes knowledge and the act of laughing at satire as protest - or worse - conceived as political action.
