If I Were Trapped on a Desert Island With Only Three Tv Series

The first two are easy, picking a third not so much.
  1. Supernatural
    I'm not too proud to admit these boys are an essential part of my daily life.
  2. Criminal Minds
    A surprising good reminder of how good working and personal relationships can/should be when you watch the underlying stories rather than the overlying crimes.
  3. Are You Being Served?
    Because Mr Humphreys and Mrs Slocombe.
