If you haven’t already clambered aboard the Ghosts train, you really should. The BBC One sitcom, about a young couple who move into a country home that’s populated by a dysfunctional family of ghosts, is created and written by, not to mention starring, the formidable comedic team of Laurence Rickard, Martha Howe-Douglas, Ben Willbond, Mathew Baynton, Jim Howick, and Simon Farnaby, and it is one of the most gloriously inventive, sweet, heartwarming and hilarious sitcoms of recent years, and is just what your 2020 needs.
