Catastrophe
Sharon Horgan and Rob Delaney on "Catastrophe"Channel 4. In its first two seasons, "Catastrophe" took big risks, but never to the level that it did in season three. The heartbreaking third season combines fresh, laugh-out-loud comedy with an honest look at a strained marriage, and ends with a shocking revelation that could completely change the direction of the show. Sharon Horgan and Rob Delaney work with the material and prove that comedy is not the only thing they're good at.
