What is your favorite TV show?

Everyone has that one TV show they love to watch and will ensure they keep up to date with it each week when it's on and each new season when it starts. I myself am a huge fan of Chicago Fire and I have watched it since it started in October 2012 even now, I will ensure I keep up tp date with the latest episode and I am often upset when I have to wait for a break between new episodes as I get so in a routine that it throws me off when I don't watch it for a few weeks.
