6. The Big C, Showtime, Monday: It doesn't get more adult than dealing with cancer. Laura Linney shows us the many ways. In the first season, it was denial. This season her character moves to anger on the grief cycle as she battles her stage 4 melanoma. British film star Hugh Dancy and independent film queen Parker Posey guest-star on the acclaimed comedy (yes, it's a comedy — mostly) this season, along with returning guest star Alan Alda. It starts June 27.
