Dexter is possibly one of the most brilliant shows around at the moment. Currently 5 seasons in, trying to explain to a newbie that you can’t just jump in mid way because every story interweaves with each other, doesn’t cut up to standards.
Instead, show them this parody video made by comedy troupe The Landline. It explains the basis of Dexter pretty easily.
Watch out for Masuka – it’s spot on!
